Description

Technical Field

[0001] This application relates to a medical device, specifically to a device for powering a portable ultrasound device. Background Technology

[0002] Portable ultrasound devices typically have built-in batteries. To increase the battery life of portable ultrasound devices, given a fixed power consumption, the only solution is to increase the battery capacity. However, increasing the battery capacity increases the size and weight of the portable ultrasound device, which reduces its flexibility in carrying and using.

[0003] Therefore, the common practice is to provide a trolley for the portable ultrasound device to increase its battery life. The trolley has a built-in battery pack and battery management circuitry, which manages battery charging and discharging. The trolley and the portable ultrasound device have an electrical interface; after the portable ultrasound device is connected to the trolley, the trolley charges the device's internal battery and simultaneously supplies power to the device.

[0004] However, the battery life of portable ultrasound devices is heavily dependent on the trolley. When hospitals do not have trolleys, or when emergency calls require trolleys, the battery life of portable ultrasound devices is limited and cannot meet the needs of emergency calls and long-term operation.

[0043] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0044] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0045] One embodiment of this application provides a portable ultrasound system; please refer to [reference needed]. Figures 1 to 3 The portable ultrasound system includes a power supply system 1000 for the portable ultrasound device and a portable ultrasound device 2000.

[0046] The portable ultrasound device 2000 can be any type of small, easily portable ultrasound device, such as a laptop ultrasound device. Users can carry the portable ultrasound device 2000 with them for ultrasound testing, improving the ease of use of ultrasound equipment.

[0047] The power supply system 1000 includes a shared battery pack 100 and a trolley 200. The shared battery pack 100 is detachably fixed to a portable ultrasound device 2000 for powering the portable ultrasound device 2000. The portable ultrasound device 2000 and the shared battery pack 100 are detachably mounted on the trolley 200. The user can remove the portable ultrasound device 2000 or the shared battery pack 100 as needed.

[0048] Specifically, the shared battery pack 100 has a first mounting part, through which it can be detachably connected to the portable ultrasound device 2000 as a whole. The first mounting part can adopt various structures that can achieve detachable fixed connection, such as snap-fit ​​structure, threaded locking structure, interference fit structure, magnetic attraction structure, and adhesive structure.

[0049] In some embodiments, the shared battery pack 100 can also be detachably and fixedly connected to the trolley 200. Therefore, a second mounting portion is provided on the outer casing that can be detachably connected to the trolley 200 as a whole. Similarly, this second mounting portion can adopt various structures that enable detachable fixed connection, such as snap-fit ​​structures, threaded locking structures, interference fit structures, magnetic attraction structures, adhesive structures, etc. Please refer to... Figure 5In one embodiment, the second mounting portion includes an unlocking port 129 provided on the side of the housing 120, which can be fixed to the snap-fit ​​structure of the trolley 200.

[0050] Of course, in some embodiments, the shared battery pack 100 may not be fixed to the trolley 200, but the shared battery pack 100 may be fixed by fixing the portable ultrasonic device 2000 to the trolley 200.

[0051] The vehicle 200 is used to charge the shared battery pack 100 and / or the portable ultrasound device 2000, and has a third mounting part that can be detachably connected to the shared battery pack 100 and / or the portable ultrasound device 2000 as a whole. Similarly, the third mounting part can also adopt various structures that can achieve detachable fixed connection, such as snap-fit ​​structure, threaded locking structure, interference fit structure, magnetic attraction structure, and adhesive structure.

[0052] The shared battery pack 100 can be fixedly mounted on the trolley 200 and electrically connected to the trolley 200, serving as the trolley 200's built-in battery. The trolley 200 can be connected to the portable ultrasound device 2000 and / or the shared battery pack 100 via an output connector to provide power. Alternatively, the trolley 200 can be used solely to support the portable ultrasound device 200 and / or the shared battery pack 100 without providing power. In special circumstances where it is inconvenient to use the trolley 200 for power, the shared battery pack 100 can be removed from the trolley 200 and fixedly connected to the portable ultrasound device 2000 as an external battery. This design eliminates the reliance of the portable ultrasound device 2000 on the trolley 200 for extended power, simplifying the process to a single shared battery pack in special situations, making it more convenient and easier to use.

[0053] In one embodiment, the shared battery pack 100 includes a battery for storing electrical energy, a first mounting portion detachably connected to a portable ultrasound device 2000, a second mounting portion battery detachably connected to a trolley 200, a charging / discharging circuit, and a control unit. The charging / discharging circuit is electrically connected to the battery, and the control unit controls the charging / discharging circuit to charge the battery and supply power to the portable ultrasound device 2000.

[0054] For details, please refer to Figures 4 to 6 In one embodiment, the shared battery pack 100 includes at least one battery 110, a housing 120, a charging / discharging circuit 130, and a control unit 140.

[0055] The battery 110 is used to store electrical energy, and there can be more than one, depending on the actual charging needs. The housing 120 has a receiving cavity in which the battery 110 is installed. The housing 120 is provided with a first mounting part that can be detachably connected to the portable ultrasonic device 2000.

[0056] The charging and discharging circuit 130 is electrically connected to the battery 110 and has a charging connector 131 and a discharging connector 132, which can be different connectors or the same connector. The charging connector 131 can be electrically connected to the adapter of the trolley 200 or the portable ultrasound host to charge the battery 110 of the shared battery pack 100. The discharging connector 132 is used to electrically connect to the portable ultrasound device 2000 to supply power to the portable ultrasound device 2000.

[0057] Please refer to Figure 4 The control unit 140 (MCU and peripheral circuits) is electrically connected to the charging and discharging circuit 130, thereby controlling the charging and discharging of the charging and discharging circuit 130. In some embodiments, the shared battery pack 100 may also include other conventional structures, such as interfaces and current detection modules, buttons and power indicator modules, etc., which will not be described in detail here.

[0058] Furthermore, in one embodiment, the charging and discharging circuit 130 has a discharge equalization circuit and a charge equalization circuit, enabling each battery 110 to discharge and charge in a balanced manner.

[0059] Furthermore, in one embodiment, the housing 120 has a support portion, allowing the portable ultrasound device 2000 to be placed on the support portion. The shared battery pack 100 provides stable support for the portable ultrasound device 2000 through this support portion. The support portion can be various support structures such as support surfaces of different shapes or brackets.

[0060] Please refer to Figure 5 and 6 Preferably, in one embodiment, the support has a support surface 121 that matches the bottom of the portable ultrasound device 2000. That is, the portable ultrasound device 2000 is mounted above the shared battery pack 100 so that the shared battery pack 100 does not interfere with the use of the portable ultrasound device 2000. Figure 7 As shown, in use, the portable ultrasound device 2000 can be placed from the support surface 121 onto the support surface 121. The design of the support surface 121 simplifies the structure of the shared battery pack 100, eliminating the need for overly complex support components. The support of the support surface 121 also increases the contact area between the shared battery pack 100 and the portable ultrasound device 2000, thereby ensuring the stability of the support.

[0061] Please refer to the following: Figure 6 The support surface 121 can be a planar structure integrally disposed on the top wall of the outer casing 120, or, please refer to Figure 5 The support surface 121 may also be composed of multiple components mounted on the top wall of the housing 120, the top walls of which together with the top wall of the housing 120 are supported under the shared battery pack 100.

[0062] Further, please refer to Figure 5 and 6 In one embodiment, the support surface 121 has a raised or recessed guide portion 122 for moving the portable ultrasound device 2000 along the guide portion 122 on the support surface 121. Figure 5 and 6 As shown, the guide portion 122 can be a guide groove. In other embodiments, the guide portion 122 can also be a guide rail or the like. The guide portion 122 is arranged along the insertion direction of the portable ultrasound device 2000, guiding the portable ultrasound device 2000 to move smoothly to the correct position.

[0063] Please refer to Figure 5 and 6 In one embodiment, the support surface 121 has a protruding first limiting portion 123, which is disposed in the insertion direction of the portable ultrasound device 2000 to limit the position of the portable ultrasound device 2000. The first limiting portion 123 may be a structure such as a protrusion, a barb, or a ridge. There may be one or more first limiting portions 123, which can limit the portable ultrasound device 2000 from one or more positions.

[0064] Please refer to Figure 5 and 6 In one embodiment, the outer casing 120 is flat, with a support surface 121 and a first mounting portion located on the top wall of the outer casing 120, so that the portable ultrasound device 2000 can be easily placed on the support surface 121. The first mounting portion (such as a first buckle 124) and the first limiting portion 123 are located on both sides of the support surface 121, allowing the shared battery pack 100 to position the portable ultrasound device 2000 from both ends. The shape of this flat structure includes, but is not limited to, polygonal, circular, and irregular shapes.

[0065] Furthermore, this first mounting part is mainly used to detachably fix the portable ultrasound device 2000 and the shared battery pack 100, thereby ensuring that the shared battery pack 100 can be integrated with the portable ultrasound device 2000 for easy carrying. Please refer to... Figure 5 , 6In one embodiment, the first mounting portion includes a first latch 124 protruding from the housing 120 for engaging with the portable ultrasound device 2000. The first latch 124 has a hook portion 1241 for engaging a corresponding structure on the portable ultrasound device 2000. The corresponding structure on the portable ultrasound device 2000 can also be a latch structure, or it can be a bayonet or locking mechanism that can be engaged by the first latch 124.

[0066] Conversely, the portable ultrasound device 2000 can also be equipped with a similar latching structure to the first latch 124 to engage the first mounting portion of the shared battery pack 100. This first mounting portion can be a bayonet, a mounting platform, or other structure.

[0067] For more specific details, please refer to Figure 5 , 6 In one embodiment, the first mounting portion has two opposing first latches 124, a first unlocking member 125 disposed between the two first latches 124, a first elastic member 126 for resetting the first latches 124, and a second elastic member 127 for resetting the first unlocking member 125.

[0068] First elastic members 126 are respectively installed in opposite directions on the two first latches 124, and the first elastic members 126 drive the two first latches 124 to move closer to each other. That is, under the drive of the two first elastic members 126, the two first latches 124 move towards the center. The first unlocking member 125 has a wide portion 1251 and a narrow portion 1252. Without the action of external force from the user, the two first latches 124 abut against the wide portion 1251 from both sides under the action of the first elastic members 126, maintaining a stable distance.

[0069] The second elastic member 127 is connected to the first unlocking member 125 and is used to hold the wide portion 1251 of the first unlocking member 125 between the two first latches 124. That is, the elastic force of the second elastic member 127 causes the wide portion 1251 of the first unlocking member 125 to move into the area between the two first latches 124.

[0070] The first unlocking member 125 protrudes from the housing 120, allowing the user to change its position so that the two first latches 124 abut against the narrow portion 1252, thus changing the distance between the two first latches 124. Depending on the configuration of the second elastic member 127, the first unlocking member 125 can move inward or outward from the housing 120, causing the wide portion 1251 of the first unlocking member 125 to move away from the area between the two first latches 124, while the narrow portion 1252 of the first unlocking member 125 moves to the area between the two first latches 124. The first elastic member 126 drives the two first latches 124 to move relative to each other, thereby abutting against the narrow portion 1252 and reducing the distance between the two first latches 124. Since the hooks 1241 of the two first buckles 124 are set in opposite directions, when the distance between the two first buckles 124 becomes smaller, the two hooks 1241 can be disengaged from the corresponding mounting part on the portable ultrasound device 2000, for example, from the bayonet of the portable ultrasound device 2000, thereby unlocking.

[0071] When it is necessary to detachably secure the portable ultrasound device 2000 to the shared battery pack 100, please refer to... Figure 5 , 6 8. When the user moves the position of the first unlocking member 125 (by pressing the first unlocking member 125 and moving it into the housing 120; in other embodiments, the first unlocking member 125 may be pulled outward), the first unlocking member 125 compresses the second elastic member 127, causing the inner wide portion 1251 to move inward and disengage from the two first latches 124, while the outer narrow portion 1252 moves inward between the two first latches 124, thereby causing the two first latches 124 to abut against the narrow portion 1252 under the influence of the first elastic member 126. At this time, the distance between the two first latches 124 becomes smaller, allowing them to be inserted into the corresponding mounting part of the portable ultrasound device 2000, such as the slot.

[0072] When the user releases the first unlocking member 125, it resets under the action of the second elastic member 127, causing the wide portion 1251 of the first unlocking member 125 to move back between the two first latches 124. This causes the two first latches 124 to open outwards, thereby engaging the corresponding mounting portion of the portable ultrasound device 2000, such as engaging the bayonet opening wall of the portable ultrasound device 2000, thus achieving a snap-fit ​​fixation. To unlock, the first unlocking member 125 can be pressed again.

[0073] Alternatively, the corresponding mounting portion of the portable ultrasound device 2000 can be directly pressed against the two first latches 124, causing the first latches 124 to apply pressure to the first unlocking member 125, overcoming the pressure of the second elastic member 127 on the first unlocking member 125, causing the first unlocking member 125 to move, and the narrow portion 1252 to move between the two first latches 124, changing the distance between the two first latches 124. When the first latches 124 are engaged with the corresponding mounting portion of the portable ultrasound device 2000, such as in the bayonet slot, the first latches 124 are released, and the second elastic member 127 will cause the first unlocking member 125 to reset, thereby causing the two first latches 124 to reopen and fasten the portable ultrasound device 2000.

[0074] An inclined guide surface may be provided between the wide portion 1251 and the narrow portion 1252 of the first unlocking member 125 to facilitate smooth movement of the wide portion 1251 and the narrow portion 1252 between the two first latches 124. The first elastic member 126 and the second elastic member 127 (and other elastic members described below) may be springs, but are not limited to springs. The first latch 124 may also be controlled in other ways, for example, the first latch 124 may be an integral structure with the first unlocking member 125 or the two may be connected by a transmission.

[0075] Please refer to Figure 8 In some embodiments, an auxiliary locking member 1281 and a vertically arranged auxiliary locking elastic member 1282 may also be provided. The auxiliary locking member 1281 is disposed on the first unlocking member 125 and is used to fix the first unlocking member 125 in the locked position. Specifically, the first unlocking member 125 has a mating part, such as a limiting port. The auxiliary locking member 1281 can be fitted onto the mating part, for example, inserted into the limiting port, to lock the first unlocking member 125 and prevent the first unlocking member 125 from moving from the locked position to the unlocked position, so as to avoid the portable ultrasound device 2000 and the shared battery pack 100 being accidentally unlocked during carrying (e.g., carried in hand), thereby causing damage to the equipment. The auxiliary locking elastic member 1282 is installed on the auxiliary locking member 1281 and provides an elastic preload to the auxiliary locking member 1281, so that the auxiliary locking member 1281 is held in the position where the first unlocking member 125 is locked. The auxiliary locking member 1281 is movably mounted on the housing 120 so that the elastic preload of the auxiliary locking member 1282 can be overcome by external force, thereby moving the position of the auxiliary locking member 1281, so that the first unlocking member 125 is unlocked, and further so that the first unlocking member 125 can be used to unlock the first latch 124.

[0076] For easy locking and unlocking of the portable ultrasound device 2000 and the shared battery pack 100, please refer to... Figure 5 and 6In one embodiment, a first latch 124 extends from the top wall of the housing 120, and a first unlocking member 125 extends from the side wall of the housing 120. The side wall of the shared battery pack 100 may have an unlocking opening 129, within which the first unlocking member 125 is disposed. When needed, the unlocking opening 129 can also serve as a second mounting portion for locking the shared battery pack 100 to the trolley 200, for example, by cooperating with the second latch mentioned later to secure the shared battery pack 100 to the trolley 200. The user can easily install the portable ultrasound device 2000 onto the top of the shared battery pack 100. When unlocking, the first unlocking member 125 can be unlocked from the side wall of the shared battery pack 100, allowing the portable ultrasound device 2000 to be removed.

[0077] Furthermore, the charging connector 131 and the discharging connector 132 can be connected to the portable ultrasound device 2000 and / or the cart 200 via wired or wireless means. Please refer to [reference needed]. Figure 5 and 6 In one embodiment, it further includes at least one first magnetic socket 133, the first magnetic socket 133 having a first magnetic element to facilitate the attraction of the portable ultrasound device 2000 and / or the trolley 200, and the charging connector 131 and the discharging connector 132 being disposed in the same or different first magnetic sockets 133 to enable power supply to the portable ultrasound device 2000 and charging of the battery 110.

[0078] The first magnetic component can attract the portable ultrasound device 2000 and / or the trolley 200 within a certain range. As long as the portable ultrasound device 2000 and / or the trolley 200 are within this range, they can be automatically attracted to the docking position by the first magnetic socket 133. Of course, the portable ultrasound device 2000 and / or the trolley 200 can be provided with a structure that magnetically engages with the first magnetic component. The first magnetic socket 133 can have a rigid wire that is upright and can swing slightly. When the portable ultrasound device 2000 and / or the trolley 200 are assembled in place, the wire automatically attracts to the connector of the portable ultrasound device 2000 and / or the trolley 200 under the action of attraction, achieving automatic insertion.

[0079] The shared battery pack 100 provided above can be used independently, or it can be used in conjunction with the trolley 200 to form a power supply system 1000, or it can be used in conjunction with the trolley 200 and the portable ultrasound device 2000 to form a portable ultrasound system.

[0080] Further, please refer to Figure 3 , 9 Up to 12, one embodiment provides a trolley 200 for a portable ultrasound device 2000. The trolley 200 includes a base 210, a support platform 220 for supporting a shared battery pack 100, a power supply 230, and a control unit 240.

[0081] The base 210 serves as the mounting base for the entire trolley 200. The support platform 220 is mounted on the base 210 and has a mounting position for placing the shared battery pack 100 and a third mounting section that can be detachably connected to the shared battery pack 100 and / or the portable ultrasonic device 2000.

[0082] The shared battery pack 100 and the portable ultrasound device 2000 are detachably mounted on the mounting position. If necessary, the portable ultrasound device 2000 can be removed or the portable ultrasound device 2000 and the shared battery pack 100 can be removed together as a whole for use.

[0083] Please refer to Figure 12 The power supply 230 can store electrical energy and can be charged by an external power supply 400. The power supply 230 has an output connector 231 for interfacing with the shared battery pack 100 or the portable ultrasound device 2000 to supply power to them. The control unit 240 is connected to the power supply 230 to control the power supply 230 to supply power to the shared battery pack 100 or the portable ultrasound device 2000.

[0084] In another embodiment, the power supply 230 may not be provided. The vehicle 200 includes a charging lead cable with an electrical input terminal and an electrical output terminal.

[0095] The second limiting part 222 can be positioned opposite the inclined side cavity wall 2211 to restrict the installation position of the shared battery pack 100. When one side of the mounting cavity 221 is open, such as Figure 9 and 11 As shown, the second limiting part 222 can be provided on this side to prevent the shared battery pack 100 from sliding off from this side.

[0096] Furthermore, this third mounting section is primarily used for the detachable fixing of the shared battery pack 100 to the trolley 200. Please refer to [reference needed]. Figure 9-11 In one embodiment, the third mounting portion has a second latch 223 for securing the shared battery pack 100. The second latch 223 has a first hook portion 2231 (the hook portion is as follows...). Figure 13 and 14 (As shown), a second mounting portion is used to fasten the shared battery pack 100. The second mounting portion can also be a snap-fit ​​structure, or it can be a latch, slot, or other structure that can be fastened by the second snap-fit ​​223.

[0097] Conversely, a similar latching structure to the second latch 223 can also be provided on the second mounting part to engage with the third mounting part of the trolley 200. This third mounting part can be a latching structure, a bayonet, or other structure.

[0098] For further information, please refer to [link / reference]. Figure 13and 14 In one embodiment, the third mounting portion further includes a third elastic member 224 and a second unlocking member 225 for resetting the second latch 223. The third elastic member 224 drives the second latch 223 to extend from the outer wall of the support platform 220 (e.g., the side cavity wall 2211 of the mounting cavity 221). The second unlocking member 225 is kinetically connected to the second latch 223 so that the user can move the second latch 223 into the support platform 220 through the second unlocking member 225.

[0099] The second unlocking component 225 and the second buckle 223 can be connected as a whole; or they can be designed separately and then connected by transmission, that is, the second unlocking component 225 can drive the second buckle 223 to move into the support platform 220, which can be achieved through various transmission structures.

[0100] In one embodiment, please refer to Figure 9 , 11 13 and 17, the mounting position is a mounting cavity 221, of which at least one side cavity wall 2211 is inclined from the outside to the inside. A second latch 223 is provided on the inclined side cavity wall 2211. The second latch 223 has a first hook portion 2231 for latching the shared battery pack 100. The top wall of the first hook portion 2231 is inclined downward to form a first guide surface to guide the shared battery pack 100 downward into the mounting cavity 221. The user can directly insert the shared battery pack 100 downward into the mounting cavity 221 along the inclined side cavity wall 2211, and press the first hook portion 2231 downward to a certain extent, so that the first hook portion 2231 and / or the second mounting portion of the shared battery pack 100 deform, so that the first hook portion 2231 is engaged with the second mounting portion of the shared battery pack 100, such as the unlocking port 129.

[0101] Alternatively, the user can drive the second unlocking member 225 to move the second latch 223 to the unlock position, then insert the shared battery pack 100 and release the second latch 223. The second latch 223 will then lock the second mounting part of the shared battery pack 100 under the action of the third elastic member 224.

[0102] When unlocking is required, the second latch 223 can be moved to the unlock position, and then the shared battery pack 100 can be removed.

[0103] Please refer to Figure 13In one embodiment, the second latch 223 is rotatably mounted within the support platform 220, and the second unlocking member 225 vertically abuts against one end of the second latch 223. A fourth elastic member 226 is provided on the second unlocking member 225, which is used to reset the second unlocking member 225 upwards. When the second unlocking member 225 is pressed downwards, the second latch 223 is driven to rotate around the pivot 227, thereby retracting the second latch 223 into the support platform 220. When the second unlocking member 225 is released, the fourth elastic member 226 drives the second unlocking member 225 to reset, while the third elastic member 224 drives the second latch 223 to reset.

[0104] In addition to rotational connection, the second buckle 223 can also be mounted on the support platform 220 by sliding or other means.

[0105] In one embodiment, the second latch 223 is slidably mounted within the support platform 220. The second unlocking member 225 and the second latch 223 are connected by a connecting body having a wide portion and a narrow portion. The second unlocking member 225 abuts against the connecting body approximately vertically, and one end of the second latch abuts against the connecting body approximately horizontally. A third elastic member 224 is arranged at the same horizontal line as the second latch and the connecting body, and the third elastic member 224 is used to reset the second latch. A fourth elastic member 226 is provided on the second unlocking member 225, and the fourth elastic member 226 is used to reset the second unlocking member 225 upwards. When the second unlocking member 225 is pressed, the connecting body moves downward, causing the second latch 223 to abut against the narrow part of the connecting body, driving the second latch 223 to retract into the support platform 220; when the second unlocking member 225 is released, the fourth elastic member 226 drives the second unlocking member 225 to reset, and the third elastic member 224 drives the second latch 223 to reset. At this time, the second latch 223 abuts against the wide part of the connecting body, and the second latch 223 can engage the shared battery pack.

[0106] Please refer to Figure 11 and 14 In one embodiment, the second latch 223 is slidably mounted on a corresponding sliding shaft 228, which is mounted on a support 229. The sliding shaft 228 and support 229 are mounted within a support platform 220, and the support 229 can be fixedly mounted on the support platform 220. A third elastic element 224 is sleeved on the sliding shaft 228 and abuts against one end of the second latch 223. The second unlocking element 225 is fixedly connected to the second latch 223 as a single unit, thus eliminating the need for a fourth elastic element 226. The third elastic element 224 is used to reset the second latch 223 and the second unlocking element 225. In this embodiment, the movement directions of the second latch 223 and the second unlocking element 225 are consistent. Please refer to... Figure 5The second unlocking member 225 can be provided in the opening 271 of the bottom housing of the support platform 200, or it can be provided in other positions of the support platform 200 for user operation.

[0107] The second clip 223 can be used solely to secure the portable ultrasound device 2000 (such as...). Figure 17 (as shown) or simultaneously secure both the portable ultrasound device 2000 and the shared battery pack 100 (as shown). Figure 13 (As shown).

[0108] For details, please refer to Figure 9 and 13 In one embodiment, the second latch 223 has a first hook portion 2231 for engaging the shared battery pack 100 and a second hook portion 2232 for engaging the portable ultrasound device 2000, with the second hook portion 2232 located above the first hook portion 2231. That is, the second latch 223 can simultaneously engage the portable ultrasound device 2000 and the shared battery pack 100. When unlocking, the portable ultrasound device 2000 and the shared battery pack 100 can be unlocked simultaneously via the second unlocking member 225.

[0109] After the portable ultrasound device 2000 and the shared battery pack 100 are installed on the trolley 200, the portable ultrasound device 2000 and the shared battery pack 100 can remain in a fixed state, or they can be in an unlocked state.

[0110] In the above embodiments, the trolley of the ultrasonic equipment may include a second mounting part for a shared battery pack, or may not include a second mounting part for a shared battery pack.

[0111] Based on the above embodiments, the second unlocking component 225 can be set in an area that the hand can touch when taking out the portable ultrasound device with one hand, so as to facilitate unlocking with one hand.

[0112] In one embodiment, the trolley includes a trolley handle connection portion 311 and a trolley handle 312, the trolley handle 312 being connected to the support platform 220 via the trolley handle connection portion 311. The trolley handle connection portion 311 includes a portion located below the handle of the portable ultrasound device and a portion that abuts against or is close to abutting against the handle of the portable ultrasound device. Please refer to... Figure 19 As shown, the second unlocking component 225 is located in the trolley handle connection section, below the handle of the portable ultrasonic device. Please refer to... Figure 20 As shown, the second unlocking member 225 is located in the trolley handle connection part, in the part that abuts or is close to abutting with the portable ultrasonic handle.

[0113] The trolley handle 312, the trolley handle connecting part 311 and / or the support part 220 can be integrally molded, or the trolley handle 312, the trolley handle connecting part 311 and / or the support part 220 can be detachable or fixed.

[0114] When a user holds the portable ultrasound device with one hand, a second unlocking element 225 can be located in multiple areas accessible to the hand to facilitate unlocking the device from the trolley with one hand. For example, please refer to...

When the user holds the handle of the portable ultrasound device 1000 with one hand, the upper surface of the trolley handle connection, the side of the trolley handle connection, the upper surface of the trolley handle, or the side of the trolley handle are all areas that the hand can reach. Setting the second unlocking button in the above-mentioned areas that can be reached with one hand makes it convenient for the operator to unlock with one hand, greatly improving the ease of use of the ultrasound device.

[0115] Of course, if the first hook 2231 engages with the unlocking port 129 of the shared battery pack 100, in one embodiment, when the shared battery pack 100 is installed on the trolley 200, the first hook 2231 can also trigger the first unlocking member 125 to move to the unlocking position, thereby unlocking the shared battery pack 100 and the portable ultrasound device 2000.

[0116] Please refer to Figure 11 , 14 -18. In one embodiment, the second latch 223 is used only to secure the portable ultrasound device 2000. In this case, to also lock the portable ultrasound device 200, the third mounting portion of the trolley 200 may also have a third latch 251, which is used to fasten the portable ultrasound device 2000. That is, the trolley 200 uses the second latch 223 to secure the shared battery pack 100 and the third latch 251 to fasten the portable ultrasound device 2000.

[0117] Please refer to Figures 14 to 18 In one embodiment, the third mounting portion further includes a fifth elastic element 252 and a third unlocking element 253 for resetting the third latch 251. The fifth elastic element 252 drives the third latch 251 to extend from the outer wall (such as the side cavity wall 2211) of the support platform 220 to fasten the portable ultrasound device 2000.

[0118] The third unlocking component 253 and the third latch 251 can be an integral structure, such as being molded as a single piece. Alternatively, the third unlocking component 253 and the third latch 251 can be designed separately, with a transmission connection between them. That is, the third unlocking component 253 can drive the third latch 251 to move into the support platform 220. This can be achieved through various transmission structures, such as... Figure 16 In this configuration, the third unlocking element 253 and the third latch 251 are fixedly connected as a single unit, both mounted on the sliding bracket 254 and driven to reset by the fifth elastic element 252. The sliding bracket 254 can be fixedly mounted within the support platform 220. In some embodiments, the third latch 251 may also be provided with a pressure adjusting bracket to adjust the preload.

[0119] The third unlocking component 253 can be placed in an area that the hand can reach when taking out a portable ultrasound device with one hand, making it convenient to unlock with one hand.

[0120] In one embodiment, based on the above embodiments, the trolley further includes a trolley handle connection part and a trolley handle, the trolley handle being connected to the support platform through the trolley handle connection part.

[0121] The third unlocking element 253 is located on the upper surface of the trolley handle connection part, the side surface of the trolley handle connection part, the upper surface of the trolley handle, or the side surface of the trolley handle. When the user holds the handle of the portable ultrasound device 1000, his / her fingers can naturally fall on the position of the third unlocking element 253, making it convenient to unlock with one hand.

[0122] Please refer to Figure 17 and 18 In a preferred embodiment, when the shared battery pack 100 and the portable ultrasound device 2000 are installed on the trolley 200, the second latch 223, which is in the locked position, can drive the first mounting part of the shared battery pack 100 to the unlocked position, so that the shared battery pack 100 and the portable ultrasound device 2000 are in an unlocked state.

[0123] For example, when the first mounting part of the shared battery pack 100 adopts such Figure 8 When the structure shown is such that the shared battery pack 100 and the portable ultrasonic device 2000 are installed on the trolley 200, as follows: Figure 17 and 18 As shown, the second latch 223 can abut against the first unlocking member 125 of the first mounting part, causing the first unlocking member 125 to drive the first latch 124 to move to the unlocked position, at which time the shared battery pack 100 and the portable ultrasound device 2000 are unlocked.

[0124] The advantage of this structure is that it allows for selection as needed: either the portable ultrasound device 2000 can be removed separately, or the shared battery pack 100 and the portable ultrasound device 2000 can be removed together as a whole. For example, the portable ultrasound device 2000 can be removed separately by controlling the third unlocking member 253; alternatively, the second unlocking member 225 can be unlocked first, which not only unlocks the shared battery pack 100 but also changes the engagement state between the shared battery pack 100 and the portable ultrasound device 2000 to a locked state, and then the third unlocking member 253 can be unlocked to remove the shared battery pack 100 and the portable ultrasound device 2000 together as a whole.

[0125] Furthermore, to more conveniently remove the shared battery pack 100 and the portable ultrasound device 2000 as a single unit, please refer to... Figure 17 and 18 In one embodiment, the third latch 251 is located on the path of the retraction of the second latch 223, so that when the second latch 223 is unlocked, the third latch 251 can move together in the unlocking direction. Therefore, when the shared battery pack 100 and the portable ultrasound device 2000 need to be removed as a whole, it is only necessary to drive the second unlocking component 225 to unlock both the second latch 223 and the third latch 251 at the same time.

[0126] like Figure 17 and 18 As shown, the second latch 223 can be located below the third latch 251. The third latch 251 is at least partially on the movement path of the second latch 223. Therefore, when the second latch 223 moves in the unlocking direction, it will inevitably collide with the third latch 251 and drive the third latch 251 to move in the unlocking direction together.

[0127] The unlocking directions of the second latch 223 and the third latch 251 can be set to be the same, or they can be set to be different. The linkage between the two can be achieved through structural design, so that the second latch 223 drives the third latch 251 to move together in the unlocking direction.

[0128] Further, please refer to Figures 17-18 In one embodiment, the mounting position has a recessed mounting cavity 221, and a third latch 251 is slidably disposed within the support platform 220.

The second hook portion 2232 is located above the first hook portion 2231. The first end of the third elastic member 224 abuts against the support platform, and the second end of the third elastic member 224 abuts against the end of the second latch 223 away from the first and second hook portions. The third elastic member 224 drives the second latch 223 to be in a locked state. The second unlocking member 225 is connected to the second latch 223 in a transmission connection, and the second latch 223 is in an unlocked state through the second unlocking member 225.

[0130] In one embodiment, based on the above embodiment, a rotating shaft 227 is further included, and a second buckle 223 is rotatably connected to the support platform with the rotating shaft as the axis.

[0131] In one embodiment, the second unlocking member 225 is vertically abutted against the end of the second buckle 223 away from the first hook and the second hook. The second unlocking member 225 is provided with a fourth elastic member 226, which is used to reset the second unlocking member 225 upward.

[0132] In one embodiment, a trolley is provided, including a base, a support platform, and a locking device.

One end of the third elastic member 224 abuts against the side wall of the support platform, and the other end of the third elastic member 224 abuts against the end of the second latch 223 away from the first hook portion. The third elastic member 221 drives the second latch 223 to be in a locked state. The second unlocking member 225 is connected to the second latch 223 in a transmission connection, and the second latch is in an unlocked state through the second unlocking member 225. The third latch 251 is located on the retraction path of the second latch 223, so that when the second latch 223 is unlocked, it can drive the third latch 251 to move together in the unlocking direction.

[0133] In one embodiment, the locking device further includes a fifth elastic element 252 for resetting the third latch and a third unlocking element 253. One end of the fifth elastic element 252 abuts against the side wall of the support platform, and the other end of the fifth elastic element abuts against the third unlocking element 253. The fifth elastic element 252 drives the third latch 251 to be in a locked state. The third unlocking element 253 is connected to the third latch 251 as a whole or through a transmission connection, so that the third latch 251 is in an unlocked state through the third unlocking element 253.
