The following embodiments are used to illustrate the present utility model, but are not used to limit the scope of the present utility model.

[0035] The orientation terms such as up, down, left, right, front, back, top, bottom, etc. (if any) involved in the description and claims of the present utility model are defined based on the positions of the structures in the accompanying drawings and their relative positions to each other, only for the sake of clarity and convenience in expressing the technical solution. It should be understood that the use of orientation terms should not limit the scope of protection claimed by the present utility model.
[0036] Such as Figures 1 to 6As shown in the figure, the transfer hospital bed provided by the embodiment of the present utility model includes a base 1 and a bed body 2 disposed above the base 1, and the bed body 2 is connected to the base 1. A driving wheel assembly 3 and a supporting wheel assembly 4 are provided below the base 1, and both the driving wheel assembly 3 and the supporting wheel assembly 4 are connected to the base 1. The base 1 is supported by the driving wheel assembly 3 and the supporting wheel assembly 4 together; the driving wheel assembly 3 has an active driving movement function, and the driving wheel assembly 3 is used to drive the base 1 to move (move forward), so that the transfer hospital bed can move actively. A pedal 5 is provided on the base 1, the pedal 5 is disposed at the side position of the base 1, the pedal 5 is movably connected to the base 1, and the pedal 5 has a deployed state and a folded state; when the pedal 5 is in the deployed state, medical staff (or accompanying family members) can stand on the pedal 5; when the pedal 5 is in the folded state, the occupied space of the pedal 5 can be reduced.
[0037] For the transfer hospital bed provided by the present utility model, by providing a driving wheel assembly 3 and a supporting wheel assembly 4 below the base 1, the driving wheel assembly 3 and the supporting wheel assembly 4 can simultaneously support the movement of the base 1, so that the base 1 has a moving function; at the same time, since the driving wheel assembly 3 has an active driving movement function, the transfer hospital bed has an active driving movement function, that is, the transfer hospital bed can move under the drive of the driving wheel assembly 3 without manual pushing, which not only saves time and effort, is beneficial to saving the treatment time, but also makes the operation of the transfer hospital bed more stable and can reduce the harm to the patient. At the same time, by providing a pedal 5 on the base 1, the pedal 5 is movably connected to the base 1, and the pedal 5 has a deployed state and a folded state; when the pedal 5 is in the deployed state, medical staff can stand on the pedal 5 and move together with the transfer hospital bed, which is convenient for medical staff to control the movement of the transfer hospital bed and is beneficial to saving the treatment time (since medical staff can move together with the transfer hospital bed, medical staff can operate the transfer hospital bed to move faster); when the pedal 5 is in the folded state, it can prevent the pedal 5 from colliding with other objects and is convenient for the storage and storage of the transfer hospital bed.
[0038] As Figure 1 、 Figure 4 and Figure 5 shown, as an implementation manner, the pedal 5 is slidably connected to the base 1, and the pedal 5 can slide horizontally relative to the base 1 to extend or retract. As Figure 4 shown, when the pedal 5 slides horizontally and retracts relative to the base 1, that is, the pedal 5 is in the folded state, at this time, the occupied space of the pedal 5 can be reduced, and the pedal 5 can be prevented from colliding with other objects; as Figure 5 shown, when the pedal 5 slides horizontally and extends relative to the base 1, that is, the pedal 5 is in the deployed state, at this time, medical staff can stand on the pedal 5 and move together with the transfer hospital bed.
[0039] Specifically, in this embodiment, a slide rail 11 is provided on the base 1. The slide rail 11 is located on the opposite sides of the pedal 5, and the pedal 5 is slidably connected to the slide rails 11 on its opposite sides. At the same time, in this embodiment, the pedal 5 is manually pushed and pulled horizontally to extend or retract; in other embodiments, a telescopic driving device (not shown in the figure, such as a telescopic driving motor, etc.) can also be provided. The telescopic driving device is connected to the pedal 5, and the pedal 5 is driven by the telescopic driving device to slide horizontally to extend or retract.
[0040] As Figure 10 and Figure 11 shown, as another implementation manner, the pedal 5 is rotatably connected to the base 1, and the pedal 5 can rotate relative to the base 1 to a horizontal state or a standing state. As Figure 10 shown, when the pedal 5 rotates relative to the base 1 to a standing state (it should be noted that this standing state can be an upward standing or a downward hanging), the pedal 5 is in a folded state; as Figure 11 shown, when the pedal 5 rotates relative to the base 1 to a horizontal state, the pedal 5 is in an unfolded state. At the same time, a locking structure (not shown in the figure) is provided on the base 1 to keep the pedal 5 in a horizontal state or a standing state.
[0041] As Figure 1 , Figure 4 and Figure 5 shown, as an implementation manner, the pedal 5 at least includes a first pedal 51 and a second pedal 52; along the left - right direction X (i.e., the width direction of the transfer hospital bed) of the transfer hospital bed, the first pedal 51 and the second pedal 52 are respectively arranged on the left and right sides of the base 1; along the front - back direction Y (i.e., the length direction of the transfer hospital bed) of the transfer hospital bed, the first pedal 51 and the second pedal 52 are respectively arranged at the front and back ends of the base 1. One medical staff can stand on the first pedal 51, and another medical staff can stand on the second pedal 52, which is beneficial to maintaining the running stability of the transfer hospital bed and preventing the transfer hospital bed from tipping over during movement. Of course, in other embodiments, along the front - back direction Y of the transfer hospital bed, the first pedal 51 and the second pedal 52 can also be both arranged at the middle position of the base 1, so as to ensure the running stability of the transfer hospital bed.
[0042] As Figure 4 and Figure 5 shown, as an implementation manner, the number of the pedals 5 is two, and the two pedals 5 are respectively arranged at the diagonal positions of the base 1. Of course, in other embodiments, the number of the pedals 5 can also be other numbers, such as four, and the four pedals 5 are respectively arranged at the four top - corner positions of the base 1.
[0043] As Figure 1 and Figure 6As shown, as an implementation, the driving wheel assembly 3 is arranged at the front end of the base 1, so as to facilitate the steering of the driving wheel assembly 3, etc., and the supporting wheel assembly 4 is arranged at the rear end of the base 1. The driving wheel assembly 3 includes a traveling driving device 31 and a driving wheel 32 connected to the traveling driving device 31 (in this embodiment, the number of driving wheels 32 is two, and the two driving wheels 32 are respectively arranged on both sides of the traveling driving device 31, that is, the two driving wheels 32 are respectively arranged on the left and right sides at the front end of the base 1). The traveling driving device 31 is fixed on the base 1, and the traveling driving device 31 is used to drive the driving wheel 32 to move, so as to drive the base 1 to move forward. The supporting wheel assembly 4 includes a supporting wheel 41 and a connecting bracket 42. The connecting bracket 42 is fixedly connected to the base 1, and the supporting wheel 41 is rotatably connected to the connecting bracket 42 (in this embodiment, the number of supporting wheels 41 and connecting brackets 42 is two, and the two supporting wheels 41 are respectively arranged on the left and right sides at the rear end of the base 1). The supporting wheel 41 can be a universal wheel, etc.
[0044] As Figure 1 and Figure 12 shown, as an implementation, the height H2 of the supporting wheel assembly 4 (H2 refers to the distance between the bottom end of the supporting wheel assembly 4 and the lower surface of the base 1) is greater than the height H1 of the driving wheel assembly 3 (H1 refers to the distance between the bottom end of the driving wheel assembly 3 and the lower surface of the base 1), so that the height of the rear end of the base 1 is greater than the height of the front end of the base 1, and further the height of the rear end of the bed body 2 is greater than the height of the front end of the bed body 2. With such a setting, when the transfer hospital bed is traveling on a flat road, after the patient lies on the bed body 2, the height of the patient's head is higher than the height of their feet (the patient's head is generally placed at the rear end of the bed body 2, and the feet are placed at the front end of the bed body 2), so as to avoid problems such as head congestion.
[0045] As Figure 1 , Figure 6 and Figure 12 shown, as an implementation, the diameter of the supporting wheel 41 is greater than the diameter of the driving wheel 32. On the one hand, it can make the height of the rear end of the base 1 greater than the height of the front end of the base 1, and because the diameter of the supporting wheel 41 is larger, it can make the movement of the transfer hospital bed more stable. Of course, in other embodiments, it can also be that the height (length) of the connecting bracket 42 is set larger, so that the height H2 of the supporting wheel assembly 4 is greater than the height H1 of the driving wheel assembly 3.
[0046] As Figures 1 to 3 shown, as an implementation, the transfer hospital bed further includes a rotating mechanism (not labeled in the figure). The rotating mechanism is arranged between the base 1 and the bed body 2. The bed body 2 is rotatably connected to the base 1 through the rotating mechanism, and the bed body 2 can rotate horizontally relative to the base 1, so that the front and rear ends of the bed body 2 can be reversed (that is, the rear end of the bed body 2 can rotate to correspond to the front end of the base 1).
[0047] Specifically, as Figure 12 shown, when the transfer hospital bed is moving forward on a flat road, the patient's head is placed at the rear end of the bed body 2, and the feet are placed at the front end of the bed body 2. At this time, the height of the patient's head is higher than the height of the feet. As Figure 13 shown, when the transfer hospital bed travels to the uphill position, if the bed body 2 still maintains the state as Figure 12 shown (that is, the rear end of the bed body 2 faces backward), then when going uphill, the height of the patient's head may be lower than the height of the feet, resulting in problems such as head congestion; to avoid this problem, by setting a rotation mechanism, the bed body 2 is rotationally connected to the base 1 through the rotation mechanism, so that the front and rear ends of the bed body 2 can be reversed; when going uphill, first rotate the rear end of the bed body 2 to the front end of the transfer hospital bed, make the patient's head face forward, and then the transfer hospital bed travels uphill. At this time, the patient's head can still maintain a height higher than the feet to avoid problems such as head congestion. After the transfer hospital bed completes the uphill movement, then rotate the bed body 2 to turn around.
[0048] As Figures 1 to 3 and Figure 7 shown, as an implementation manner, the rotation mechanism includes a rotation driving mechanism 6. Along the front-rear direction Y and the left-right direction X of the transfer hospital bed, the rotation driving mechanism 6 is arranged at the middle position of the transfer hospital bed (ensuring that the bed body 2 can still be aligned with both ends of the base 1 after turning around). The rotation driving mechanism 6 includes a rotation driving device 61 and a rotation rod 62. The rotation driving device 61 is fixedly arranged on the base 1. One end (bottom end) of the rotation rod 62 is connected to the rotation driving device 61, and the other end (top end) of the rotation rod 62 is fixedly connected to the bed body 2; the rotation driving device 61 is used to drive the rotation rod 62 to rotate, thereby driving the bed body 2 to rotate. In this embodiment, the rotation driving device 61 is a rotary table (specifically a hollow rotary platform device); of course, in other embodiments, the rotation driving device 61 can also be a rotation driving motor, etc.
[0049] As Figures 1 to 3 and Figure 8As shown, as an implementation manner, the rotation mechanism further includes a rotation support mechanism 7. The rotation support mechanism 7 includes a slewing bearing 71 and a support member 72. The slewing bearing 71 includes an inner ring 711, an outer ring 712 sleeved outside the inner ring 711, and rolling elements 713 (the rolling elements 713 are specifically balls) disposed between the inner ring 711 and the outer ring 712. The inner ring 711 can rotate relative to the outer ring 712 (for the specific structure of the slewing bearing 71, reference can be made to the prior art). The rotation support mechanism 7 is sleeved on the periphery of the rotation driving mechanism 6 (that is, the rotation driving mechanism 6 is disposed inside the rotation support mechanism 7). The slewing bearing 71 is disposed on the base 1, the outer ring 712 is fixedly connected to the base 1, one end of the support member 72 is fixedly connected to the inner ring 711, and the other end of the support member 72 is fixedly connected to the bed body 2, that is, the support member 72 can rotate relative to the outer ring 712. Of course, in other embodiments, the slewing bearing 71 can also be disposed on the bed body 2, the outer ring 712 is fixedly connected to the bed body 2, one end of the support member 72 is fixedly connected to the inner ring 711, and the other end of the support member 72 is fixedly connected to the base 1. By providing the rotation support mechanism 7, it can not only support the bed body 2, but also enable the bed body 2 to rotate more smoothly.
[0050] As Figures 1 to 3 and Figure 8 shown, as an implementation manner, the support member 72 is a support cylinder (not labeled in the figure) sleeved on the periphery of the rotating rod 62. The support cylinder is of a cylindrical structure and is coaxially arranged with the rotating rod 62. By setting the support member 72 as a cylindrical structure, it can not only better play a supporting role, but also play a role in sealing and shielding the rotation driving mechanism 6 (that is, the rotation driving mechanism 6 is sealed inside the support cylinder), improve the service life of the rotation driving mechanism 6, and improve the aesthetic degree. Of course, in other embodiments, the support member 72 can also be in the form of a plurality of support rods.
[0051] As Figure 8 shown, as an implementation manner, a first stop portion 73 and a second stop portion 74 are provided on the outer ring 712. The first stop portion 73 and the second stop portion 74 are arranged at intervals; a limiting portion 75 is provided on the support member 72 (specifically, the limiting portion 75 is provided on the outer wall of the support cylinder). Both the first stop portion 73 and the second stop portion 74 are located on the rotation path of the limiting portion 75. When the bed body 2 rotates to a position where its front end corresponds to the front end of the base 1, the limiting portion 75 can abut against the first stop portion 73; when the bed body 2 rotates to a position where its front end corresponds to the rear end of the base 1, the limiting portion 75 can abut against the second stop portion 74, thereby further limiting the rotation angle of the bed body 2 and preventing the bed body 2 from rotating excessively (although the rotation driving mechanism 6 itself has a rotation angle limiting function, providing this stop structure can further prevent the bed body 2 from rotating excessively).
[0052] As Figure 9As shown, as an implementation manner, the transfer hospital bed further includes a control module 8 and a remote control device 9. The control module 8 is disposed on the base 1 (the control module 8 may specifically be a PLC, etc.). The control module 8 is electrically connected to the drive wheel assembly 3 and the rotation drive mechanism 6 by electrical signals (specifically, the control module 8 is electrically connected to the traveling drive device 31 and the rotation drive device 61 by electrical signals). The control module 8 is used to control the traveling movement of the drive wheel assembly 3 and the rotation movement of the rotation drive mechanism 6. The remote control device 9 is signal-connected to the control module 8, and medical staff can control the traveling movement and rotation movement of the transfer hospital bed through the remote control device 9.
[0053] Specifically, the traveling drive device 31 includes a traveling drive module, a steering module, a braking module, etc. The traveling drive module is used to drive the drive wheel 32 to move forward. The steering module is used to control the steering of the drive wheel 32. The braking module is used to control the braking and release of the drive wheel 32 to achieve the braking purpose. The control module 8 is electrically connected to the traveling drive module, the steering module, and the braking module by electrical signals to control the forward movement, steering, and braking of the transfer hospital bed, etc. The remote control device 9 and the control module 8 can be signal-connected by a cable (i.e., a wired connection), or can be a wireless communication connection (such as through infrared remote control, Bluetooth remote control, etc.); when the transfer hospital bed is moving, medical staff can stand on the pedal 5 to remotely control the transfer hospital bed.
[0054] As an implementation manner, the transfer hospital bed further includes a storage battery (not shown in the figure). The storage battery is disposed on the base 1. The storage battery is electrically connected to the control module 8, the drive wheel assembly 3, and the rotation drive mechanism 6 to supply power to the transfer hospital bed.
[0055] The transfer hospital bed provided by the embodiment of the present invention, by providing the drive wheel assembly 3 and the support wheel assembly 4 below the base 1, the drive wheel assembly 3 and the support wheel assembly 4 can simultaneously move and support the base 1, so that the base 1 has a moving function; at the same time, since the drive wheel assembly 3 has an active driving and moving function, the transfer hospital bed has an active driving and moving function, that is, the transfer hospital bed can move under the drive of the drive wheel assembly 3 without manual pushing, which not only saves time and effort, is beneficial to saving the treatment time, but also makes the operation of the transfer hospital bed more stable and can reduce the harm to the patient. At the same time, by providing a pedal 5 on the base 1, the pedal 5 is movably connected to the base 1, and the pedal 5 has a deployed state and a folded state; when the pedal 5 is in the deployed state, medical staff can stand on the pedal 5 and move together with the transfer hospital bed, which is convenient for medical staff to control the movement of the transfer hospital bed and is beneficial to saving the treatment time; when the pedal 5 is in the folded state, it can prevent the pedal 5 from colliding with other objects and is convenient for the storage and storage of the transfer hospital bed.
[0056] The above are only the specific implementation manners of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of changes or substitutions, which should all be covered within the protection scope of the present utility model.
