[0050] It can be seen that the trolley power supply system can provide power for portable medical equipment in a timely and convenient manner when there is no mains power. When there is no trolley, an independent shared battery pack can be used to charge the portable medical equipment for battery life, so that the battery life of the portable medical equipment is not completely dependent on the trolley and mains power. In addition, when there is no mains power, whether the portable medical equipment is installed on the trolley or not, the shared battery pack can be used to directly power the portable medical equipment for battery life. There is no need to replace the built-in battery of the portable medical equipment after the built-in battery of the portable medical equipment is discharged, which avoids the operation of shutting down the portable medical equipment and replacing the battery during use. Therefore, without affecting the normal use of the portable medical equipment, the power life of the portable medical equipment is flexible and convenient, and the battery life of the portable medical equipment in various usage scenarios is improved.

[0051] The trolley provided by the present invention is provided with a detachable mounting portion for a shared battery pack, and the second connecting terminal of the trolley is used to be electrically connected to the third connecting terminal of the shared battery pack. Therefore, when there is AC power, the portable medical device can be powered by the trolley; when there is no AC power, the portable medical device can be powered by the shared battery pack installed in the mounting portion and electrically connected to the second connecting terminal. That is, in the absence of AC power, the portable medical device can be powered in a timely and convenient manner.

[0052] The portable medical system provided by the present invention includes any one of the above-mentioned trolley power supply systems and has the same beneficial effects as the trolley power supply system. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0067] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0068] The core of the present invention is to provide a trolley power supply system that can promptly and conveniently provide power to portable medical devices when the trolley is not available. Another core of the present invention is to provide a trolley that can facilitate the timely and convenient power supply of portable medical devices through a shared battery pack connected to the second connection terminal when there is no mains power. Another core of the present invention is to provide a portable medical system including the above-mentioned trolley power supply system that can promptly and conveniently provide power to portable medical devices when the trolley is not available.

[0069] Please refer to Figure 1 and Figure 2 The embodiment of the utility model provides a trolley power supply system, including a trolley 1 and a shared battery pack 2. The trolley 1 is used to carry portable medical equipment. The trolley 1 is provided with a power supply management module and a power socket 11, a first connection terminal and a second connection terminal 121 electrically connected to the power supply management module respectively. The first connection terminal is used to electrically connect to the portable medical equipment; the shared battery pack 2 is detachably provided on the trolley 1, and the shared battery pack 2 is provided with a third connection terminal 21 (such as Figure 4 As shown) and a charging interface (located at a preset position of the shared battery pack 2, for example, located on the side of the shared battery pack 2, not shown in the accompanying drawings), the third connection terminal 21 is used to be electrically connected to the second connection terminal 121, and the charging interface is used to be electrically connected to the portable medical device; when the third connection terminal 21 is electrically connected to the second connection terminal 121, the power supply management module is used to power the portable medical device through the AC power when the power socket 11 is connected to the AC power, and to charge the shared battery pack 2 that is not fully charged, and is also used to power the portable medical device through the shared battery pack 2 when the power socket 11 is not connected to the AC power; when the charging interface is electrically connected to the portable medical device, the portable medical device is powered by the shared battery pack 2. In order to facilitate the electrical connection of the charging interface with the portable medical device, in some embodiments, the charging interface can be electrically connected to the portable medical device through a charging cable. In this way, the portable medical device can be conveniently charged through the shared battery pack 2.

[0070] That is to say, the shared battery pack 2 in this embodiment can be mounted on the trolley 1, carried by the trolley 1, and circulated with the trolley 1. The shared battery pack 2 can also be removed from the trolley 1 and exist independently of the trolley 1. When the portable medical device is placed on the trolley 1, the shared battery pack 2 is also provided on the trolley 1, so that the shared battery pack 2 and the portable medical device circulate with the trolley 1 at the same time. In this case, when the power socket 11 is capable of connecting to the mains, the power socket 11 can be connected to the mains, and the mains can be used to directly power the portable medical device through the first connection terminal of the trolley 1 via the power supply management module. At this time, if the shared battery pack 2 is not fully charged, the shared battery pack 2 can also be charged simultaneously by the mains through the power supply management module through the connection between the third connection terminal 21 and the second connection terminal 121. When the portable medical device and the shared battery pack 2 are both installed on the trolley 1, and the power socket 11 is not capable of connecting to the mains power, the shared battery pack 2 can be connected through the second connection terminal 121 and the third connection terminal 21, and through the power supply management module, the first connection terminal of the trolley 1 can be used to provide power for the portable medical device. That is, even in the absence of mains power, the portable medical device can be powered in a timely and convenient manner. When the trolley 1 is not available or cannot be configured, such as in an emergency medical visit, the charging port of the shared battery pack 2 removed from the trolley 1 can be electrically connected to the portable medical device, and the shared battery pack 2 can directly charge the portable medical device.

[0071] It can be seen that the trolley power supply system provided in the embodiment of the present invention can provide power for portable medical equipment in a timely and convenient manner even in the absence of mains power. When the trolley 1 is not available, an independent shared battery pack 2 can be used to charge and sustain the portable medical equipment, so that the battery life of the portable medical equipment is not completely dependent on the trolley 1 and the mains power. In addition, in the absence of mains power, whether the portable medical equipment is installed on the trolley 1 or not, the shared battery pack 2 can be used to directly power and sustain the portable medical equipment. There is no need to replace the built-in battery of the portable medical equipment after the built-in battery of the portable medical equipment is discharged, which avoids the operation of shutting down the portable medical equipment and replacing the battery during use. Therefore, without affecting the normal use of the portable medical equipment, the power life of the portable medical equipment is flexible and convenient, and the battery life of the portable medical equipment in various usage scenarios is improved.

[0072] It should be noted that this embodiment does not limit the specific structure of the power supply management module and its functional implementation method, as long as it can implement the power supply configuration for the portable medical device described above.

[0073] Please combine Figure 2 and Figure 3In some embodiments, the power supply management module includes a battery adapter 12 and a battery management component 13. The second connection terminal 121 is provided on the battery adapter 12, and the battery adapter 12 is electrically connected to the battery management component 13. The battery management component 13 is electrically connected to the power socket 11 through a first cable, and the battery management component 13 is electrically connected to the first connection terminal through a second cable. That is to say, in this embodiment, the shared battery pack 2 is electrically connected to the battery adapter 12, and is indirectly connected to the battery management component 13 through the battery adapter 12. In this way, it is convenient to arrange the battery adapter 12 and the battery management component 13 at appropriate positions on the trolley 1 respectively. At the same time, it is convenient to adapt to the setting position of the shared battery pack 2 and facilitate the connection between the shared battery pack 2 and the power supply management module. It should be noted that this embodiment does not limit the specific structure and function of the battery adapter 12 and the battery management component 13 respectively, as long as the two cooperate to achieve the power supply configuration for the portable medical device described above. In some embodiments, the battery adapter 12 and the battery management component 13 are both plate-shaped components, that is, the battery adapter 12 is a battery adapter board, and the battery management component 13 is a battery management board. The plate-shaped components are conducive to the rational layout of circuits and electronic components, and are convenient for setting mechanical limit structures, etc., and are convenient for positioning and installation.

[0074] Furthermore, please combine Figure 1 、 Figure 2 and Figure 3 In some embodiments, the power supply management module is provided at the base 17 of the trolley 1, and the trolley 1 includes a column 19 vertically connected to the base 17, and the second cable is provided along the column 19 to be electrically connected to the first connection terminal provided on the top of the trolley 1. It can be understood that the base 17 of the trolley 1 usually has a large structural space, which is convenient for the installation of the power supply management module; in addition, the second cable is provided along the column 19, and the column 19 is used to guide the second cable, so as to facilitate the electrical connection of the second cable with the first connection terminal on the top of the trolley 1. In some embodiments, the power supply management module is provided inside the base 17, and the second cable is provided inside the column 19. That is, the power supply management module and the second cable are both hidden designs, which is convenient for protecting the power supply management module and the second cable.

[0075] In addition, this embodiment does not limit the specific setting position of the shared battery pack 2 on the trolley 1. For example, the shared battery pack 2 can be set at a position where the base 17 of the trolley 1 is located behind the column 19 of the trolley 1, or it can be set at a position where the base 17 of the trolley 1 is located in front of the column 19. Of course, it can also be set on the column 19.

[0076] In addition, when placing the shared battery pack 2 on the trolley 1, in order to ensure the accuracy of the position of the shared battery pack 2, please combine Figure 4 and Figure 5In some embodiments, the shared battery pack 2 is provided with a guide hole 22, and the trolley 1 is provided with a guide post 14. The guide post 14 is used to cooperate with the guide hole 22 for limiting position. That is, when the shared battery pack 2 is installed on the trolley 1, the guide hole 22 is aligned with the guide post 14, and the guide hole 22 is inserted into the guide post 14. The cooperation between the guide post 14 and the guide hole 22 is used to limit the position of the shared battery pack 2 so that the third connection terminal 21 of the shared battery pack 2 can be accurately connected with the second connection terminal 121 on the battery adapter 12, ensuring the reliability of the electrical connection.

[0077] Furthermore, in some embodiments, the guide post 14 is also used to secure the battery adapter 12. That is, the battery adapter 12 is limited and secured to the trolley 1 by the guide post 14. It can be seen that the guide post 14 can achieve multiple uses with one structure, thereby simplifying the structure. It is understandable that because the guide post 14 is also used to secure the battery adapter 12, the guide post 14 is relatively close to the second connection terminal 121. Therefore, through the cooperation between the guide post 14 and the guide hole 22, the shared battery pack 2 can be precisely positioned, thereby improving the accuracy of the position of the shared battery pack 2.

[0078] In addition, when the shared battery pack 2 is placed on the trolley 1, in order to quickly locate the shared battery pack 2 and ensure the correctness of its installation position, please refer to Figure 6 In some embodiments, one of the trolley 1 and the shared battery pack 2 is provided with a guide rib 23 arranged in the vertical direction, and the other is provided with a guide groove 15 with a top opening and used to cooperate with the guide rib 23 for limiting the position. That is to say, when the shared battery pack 2 is placed into the trolley 1, the guide rib 23 is aligned and plugged into the guide groove 15, and the guide groove 15 is used to guide and limit the guide rib 23 to ensure that the shared battery pack 2 is smoothly placed downward into the trolley 1, ensuring the accuracy of the position of the shared battery pack 2. It can be understood that the cooperation between the guide rib 23 and the guide groove 15 is used to achieve rough positioning of the shared battery pack 2, which facilitates the rapid positioning and installation of the shared battery pack 2 during installation. In some embodiments, the guide ribs 23 are provided on both sides of the shared battery pack 2, and the guide groove 15 is provided on the side wall of the battery compartment 16 for installing the shared battery pack 2.

[0079] In addition, after the shared battery pack 2 is installed on the trolley 1, in order to prevent the shared battery pack 2 from moving upward during the transfer of the trolley 1, in some embodiments, the trolley power supply system further includes a locking device, which is provided on at least one of the trolley 1 and the shared battery pack 2, and is used to lock the shared battery pack 2 when the shared battery pack 2 is installed on the trolley 1. That is to say, after the shared battery pack 2 is installed on the trolley 1, the locking device is used to lock the shared battery pack 2 and the trolley 1 to each other, so as to achieve the relative fixation of the position of the shared battery pack 2 and the trolley 1, avoid the shared battery pack 2 from moving upward during the transfer of the trolley 1, and avoid the risk of the shared battery pack 2 falling off the trolley 1, thereby ensuring the reliability of the position of the shared battery pack 2. It should be noted that the locking device can be provided only on the trolley 1 or only on the shared battery pack 2. For example, the locking device is an elastic claw. When the shared battery pack 2 is installed on the trolley 1, the shared battery pack 2 is squeezed under the action of gravity to move the claw outward. When the shared battery pack 2 is installed in place, the claw's own elastic restoring force is used to always keep the claw clamped on the side wall of the shared battery pack 2 or the trolley 1, thereby achieving the locking and fixation of the shared battery pack 2 and the trolley 1. Of course, in order to improve the reliability of the locking of the shared battery pack 2 and the trolley 1, the locking device can have a part of its structure located on the shared battery pack 2 and another part of its structure located on the trolley 1.

[0080] Please refer to Figure 7 、 Figure 8 and Figure 9In some embodiments, the locking device includes a first clip 31, a second clip 32, a first elastic member 33 and two slots 34. The first clip 31 and the second clip 32 are arranged opposite to each other and are slidably provided on the trolley 1. The tops of the two clips are respectively provided with guide slopes 311 or guide arc surfaces for contacting the bottom of the shared battery pack 2, so that the first clip 31 and the second clip 32 are moved away from each other by the gravity of the shared battery pack 2; the first elastic member 33 is connected between the first clip 31 and the second clip 32, and the first elastic member 33 is used to provide elastic force to the first clip 31 and the second clip 32 respectively so that the first clip 31 and the second clip 32 are close to each other; the two slots 34 are respectively provided on two opposite side walls of the shared battery pack 2, and are used to respectively engage with the first clip 31 and the second clip 32. That is, when the shared battery pack 2 is installed on the trolley 1, the bottom of the shared battery pack 2 pushes against the guide inclined surface 311 or the guide arc surface, causing the first snap 31 and the second snap 32 to move away from each other, so that the first snap 31 and the second snap 32 give way to the shared battery pack 2, and the shared battery pack 2 is installed in place; during this process, the first snap 31 and the second snap 32 stretch the first elastic member 33, causing the first elastic member 33 to generate an elastic force. When the shared battery pack 2 is installed in place, under the action of the elastic force of the first elastic member 33, the first snap 31 and the second snap 32 are moved closer to each other and respectively snapped into the two slots 34 on both sides of the shared battery pack 2. The first snap 31 and the second snap 32 are respectively fixed to the corresponding slots 34, thereby locking the shared battery pack 2 to the trolley 1. At this time, the shared battery pack 2 cannot move upward. This locking device can automatically lock the shared battery pack 2 during installation, which is convenient to use. It should be noted that this embodiment does not limit the specific structure of the first elastic member 33. In some embodiments, the first elastic member 33 includes a spring.

[0081] Further, when the shared battery pack 2 is removed from the trolley 1, in order to facilitate the unlocking of the first buckle 31 and the second buckle 32 from the two slots 34, please continue to refer to Figure 8 and Figure 9In some embodiments, the locking device further includes a first connecting rod 35, a second connecting rod 36 and an unlocking member 37, wherein the first connecting rod 35 is rotatably connected to the first buckle 31; the second connecting rod 36 is rotatably connected to the second buckle 32; the unlocking member 37 is rotatably connected to the first connecting rod 35 and the second connecting rod 36 respectively, and the unlocking member 37 is used to withstand the pressing force so as to drive the first connecting rod 35 and the second connecting rod 36 to rotate, so that the first buckle 31 and the second buckle 32 move away from each other. That is, when the shared battery pack 2 needs to be removed from the trolley 1, a pressing force is applied to the unlocking member 37, causing the unlocking member 37 to transmit the pressing force to the first connecting rod 35 and the second connecting rod 36, respectively, thereby driving the first connecting rod 35 and the second connecting rod 36 to rotate. After the first connecting rod 35 and the second connecting rod 36 rotate, their positions change, and the first connecting rod 35 pushes the first latch 31, and the second connecting rod 36 pushes the second latch 32, thereby moving the first latch 31 and the second latch 32 away from each other, causing the first latch 31 and the second latch 32 to disengage from the corresponding latch slots 34, thereby unlocking the locking device. In other words, when the shared battery pack 2 needs to be removed from the trolley 1, only the unlocking member 37 needs to be pressed to unlock the locking device, allowing the shared battery pack 2 to be removed from the trolley 1. This unlocking method is simple and easy to operate. It is understandable that the unlocking member 37 is exposed on the outside of the trolley 1 and is located in a position that is convenient to press. It should be noted that this embodiment does not specifically limit the rotational connection structure between the first connecting rod 35 and the first buckle 31, between the second connecting rod 36 and the second buckle 32, and between the unlocking member 37 and the first connecting rod 35 and the second connecting rod 36, respectively. As long as relative rotation between the two rotationally connected structural members can be achieved, it is sufficient. In some embodiments, the first connecting rod 35 and the first buckle 31, the second connecting rod 36 and the second buckle 32, and the unlocking member 37 and the first connecting rod 35 and the second connecting rod 36 are all connected by a pin 39. It is understood that the two structural members connected by the pin 39 can each rotate about the pin 39, thereby achieving relative rotation between the two structural members. This connection structure is simple and easy to connect.

[0082] In addition, in order to ensure the smoothness of the movement of the first buckle 31 and the second buckle 32 when they move away from or approach each other, please continue to refer to Figure 8 and Figure 9In some embodiments, the trolley 1 is provided with a guide rail 38 for forming a guide groove, and the first clip 31 and the second clip 32 are respectively provided in the guide groove, and the guide rail 38 is provided with a limiting portion 381 for limiting the first clip 31 and the second clip 32 to prevent the first clip 31 and the second clip 32 from being separated from the guide groove. In other words, when the first clip 31 and the second clip 32 move away from each other under the gravity of the shared battery pack 2, or when they move closer to each other under the elastic force of the first elastic member 33, the first clip 31 and the second clip 32 respectively move in the guide groove. The guide groove defines the sliding direction of the first clip 31 and the second clip 32, guides the movement of the first clip 31 and the second clip 32, and thus ensures the stability and smoothness of the movement of the first clip 31 and the second clip 32. It can be understood that the limiting portion 381 limits the first clip 31 and the second clip 32 respectively to prevent the first clip 31 and the second clip 32 from escaping from the guide groove, which is conducive to ensuring the reliability of the first clip 31 and the second clip 32 respectively connected to the guide groove.

[0083] In addition, to facilitate the configuration of shared battery pack 2, please refer to Figure 2 、 Figure 10 and Figure 11 In some embodiments, the trolley 1 is provided with a battery compartment 16 (the battery compartment 16 can be provided on the column 19 or the base 17). The shared battery pack 2 is detachably provided within the battery compartment 16, and a retractable compartment door 161 is provided at the opening of the battery compartment 16. In other words, this embodiment provides the battery compartment 16 on the trolley 1 to accommodate the shared battery pack 2. On the one hand, the battery compartment 16 provides a certain limit to the shared battery pack 2, facilitating the rapid positioning and installation of the shared battery pack 2 during installation. On the other hand, the shared battery pack 2 can be at least partially concealed within the battery compartment 16, providing a certain degree of protection. Furthermore, after the shared battery pack 2 is removed from the battery compartment 16, to prevent foreign matter from falling into the battery compartment 16 and affecting its re-entry into the battery compartment 16, this embodiment provides a retractable compartment door 161 at the opening of the battery compartment 16 to protect the battery compartment 16. It can be understood that when the shared battery pack 2 is taken in or out, the compartment door 161 is opened to facilitate the shared battery pack 2 to pass through the compartment door 161. When the shared battery pack 2 is put in or taken out, the compartment door 161 is closed to protect the shared battery pack 2 or the battery compartment 16 and prevent foreign objects from falling into the battery compartment 16.

[0084] In addition, it is understandable that when the trolley 1 is provided with a battery compartment 16 , the battery adapter 12 is provided at the bottom of the battery compartment 16 to facilitate electrical connection between the shared battery pack 2 and the battery adapter 12 .

[0085] For further information, please refer to Figure 11In some embodiments, the base 17 is provided with a base cover 171, and the compartment door 161 is rotatably connected to the base cover 171. A second elastic member 18 is disposed between the compartment door 161 and the base cover 171. The second elastic member 18 is used to provide an elastic force to the compartment door 161 to close the compartment opening. It is understood that when the shared battery pack 2 is to be placed, the shared battery pack 2 will first push the compartment door 161 open under the action of gravity to allow the shared battery pack 2 to be placed into the battery compartment 16. During this process, the compartment door 161 compresses or stretches the second elastic member 18, generating an elastic force. When the shared battery pack 2 is removed from the battery compartment 16, the compartment door 161 is released. The elastic force of the second elastic member 18 causes the compartment door 161 to automatically close after removal, facilitating easy use. It should be noted that the specific structure of the second elastic member 18 is not limited in this embodiment. In some embodiments, the second elastic member 18 comprises a torsion spring.
