The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0045] In one embodiment of the present application, a portable ultrasound system is provided. Figures 1 to 3 The portable ultrasound system includes a power supply system 1000 for a portable ultrasound device and a portable ultrasound device 2000.

[0046] The portable ultrasonic device 2000 can be any small ultrasonic device that is easy to carry, such as a notebook ultrasonic device. The user can carry the portable ultrasonic device 2000 with him / her for ultrasonic testing, thereby improving the convenience of using the ultrasonic device.

[0047] The power supply system 1000 includes a shared battery pack 100 and a trolley 200. The shared battery pack 100 can be detachably fixed to the portable ultrasound device 2000 to power the portable ultrasound device 2000. The portable ultrasound device 2000 and the shared battery pack 100 can be 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 portion, through which the shared battery pack 100 can be detachably connected to the portable ultrasound device 2000 as a whole. The first mounting portion can adopt various structures that can achieve detachable fixed connection, such as a snap-fit ​​structure, a threaded locking structure, an interference fit structure, a magnetic attraction structure, and an adhesive structure.

[0049] In some embodiments, the shared battery pack 100 can also be detachably fixedly connected to the trolley 200. Therefore, a second mounting portion that can be detachably connected to the trolley 200 as a whole is provided on the housing. Similarly, the second mounting portion can adopt various structures that can achieve detachable fixed connection, such as a snap-fit ​​structure, a threaded locking structure, an interference fit structure, a magnetic attraction structure, an adhesive structure, etc. Please refer to Figure 5In one embodiment, the second mounting portion includes an unlocking port 129 opened on the side of the housing 120 , and the unlocking port 129 can be fixed with 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 ultrasound device 2000 to the trolley 200 .

[0051] The trolley 200 is used to charge the shared battery pack 100 and / or the portable ultrasound device 2000, and has a third mounting portion that can be detachably connected to the shared battery pack 100 and / or the portable ultrasound device 2000 as a whole.

[0052] The shared battery pack 100 can be fixedly mounted on the trolley 200, electrically connected to the trolley 200, and used as a built-in battery of the trolley 200. The trolley 200 can be connected to the portable ultrasound device 2000 and / or the shared battery pack 100 through the output connector to provide power endurance. Alternatively, the trolley 200 can also be used only to support the portable ultrasound device 200 and / or the shared battery pack 100 without providing power endurance. In special circumstances, when it is inconvenient to use the trolley 200 for power supply, 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 for the portable ultrasound device 2000. This design makes the portable ultrasound device 2000 no longer rely on the trolley 200 to increase battery life. In special circumstances, it can be simplified to only one shared battery pack, which is more convenient and easier to use.

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

[0054] Specifically, 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 charge and discharge circuit 130 , and a control unit 140 .

[0055] The battery 110 is used to store electric energy, and there may be more than one battery 110, which may be selected according to actual charging requirements. The housing 120 has a receiving cavity, and the battery 110 is installed in the receiving cavity. The housing 120 is provided with a first mounting portion that can be detachably connected to the portable ultrasound device 2000.

[0056] The charge and discharge circuit 130 is electrically connected to the battery 110, and has a charging connector 131 and a discharging connector 132, wherein the charging connector 131 and the discharging connector 132 can be different connectors or the same connector. The charging connector 131 can be electrically connected to the trolley 200 or the adapter of the portable ultrasound host to charge the battery 110 of the shared battery pack 100. The discharging connector 132 is used to be electrically connected 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 charge and discharge circuit 130, so as to control the charge and discharge of the charge and discharge circuit 130. In some embodiments, the shared battery pack 100 may also include some other conventional structures, such as an interface and current detection module, a button and a power indicator light module, etc., which will not be described in detail here.

[0058] Furthermore, in one embodiment, the charge-discharge circuit 130 has a discharge equalization circuit and a charge equalization circuit, so that each battery 110 can be discharged and charged in a balanced manner.

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

[0060] Please refer to Figure 5 and 6 Preferably, in one embodiment, the support portion has a support surface 121 that matches the bottom of the portable ultrasound device 2000. That is, the portable ultrasound device 2000 is installed above the shared battery pack 100, so that the shared battery pack 100 does not affect the use of the portable ultrasound device 2000. Figure 7 As shown, when in use, the portable ultrasound device 2000 can be placed from the support surface 121 to the support surface 121. The design of the support surface 121 can simplify the structure of the shared battery pack 100, without the need to set an overly complex support part. The support of the support surface 121 can also increase the contact area between the shared battery pack 100 and the portable ultrasound device 2000, thereby ensuring the stability of the support.

[0061] Among them, please refer to Figure 6 The support surface 121 may be a planar structure integrally disposed on the top wall of the housing 120, or, please refer to Figure 5 The support surface 121 may also be composed of a plurality of components mounted on the top wall of the outer shell 120 , and the top walls of these components and the top wall of the outer shell 120 are supported together at the bottom of the shared battery pack 100 .

[0062] For further information, please refer to Figure 5 and 6 In one embodiment, the support surface 121 has a convex or concave guide portion 122, so that the portable ultrasound device 2000 can move along the guide portion 122 on the support surface 121. Figure 5 and 6 As shown, the guide portion 122 may be a guide groove. In other embodiments, the guide portion 122 may also be a guide rail, etc. The guide portion 122 is arranged along the insertion direction of the portable ultrasound device 2000 to guide 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 raised first limiting portion 123, which is arranged in the insertion direction of the portable ultrasonic device 2000 to limit the position of the portable ultrasonic device 2000. The first limiting portion 123 can be a structure such as a convex block, a barb or a convex ridge. There can be more than one first limiting portion 123, and the portable ultrasonic device 2000 can be limited from one or more positions.

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

[0065] Furthermore, the first mounting portion 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. Figure 5 , 6In one embodiment, the first mounting portion includes a first buckle 124 protruding from the housing 120, and the first buckle 124 is used to engage with the portable ultrasound device 2000. The first buckle 124 has a hook portion 1241 for engaging with a corresponding structure on the portable ultrasound device 2000. The corresponding structure on the portable ultrasound device 2000 may also be a buckle structure, or may also be a bayonet or a bayonet structure that can be buckled by the first buckle 124.

[0066] Of course, conversely, a buckle structure similar to the first buckle 124 may also be provided on the portable ultrasound device 2000 to buckle the first mounting portion of the shared battery pack 100. The first mounting portion may be a bayonet, a bayonet platform or other structures.

[0067] For more details, please refer to Figure 5 , 6 And 8, in one embodiment, the first mounting portion has two oppositely arranged first buckles 124, a first unlocking member 125 arranged between the two first buckles 124, a first elastic member 126 driving the first buckles 124 to reset, and a second elastic member 127 driving the first unlocking member 125 to reset.

[0068] First elastic members 126 are respectively installed in the directions in which the two first buckles 124 are separated from each other, and the first elastic members 126 drive the two first buckles 124 to approach each other. That is, driven by the two first elastic members 126, the two first buckles 124 move toward the middle. The first unlocking member 125 has a wide portion 1251 and a narrow portion 1252. Without the external force of the user, the two first buckles 124 press against the wide portion 1251 from both sides under the action of the first elastic members 126 to maintain a stable spacing.

[0069] The second elastic member 127 is connected to the first unlocking member 125 and is used to keep the wide portion 1251 of the first unlocking member 125 between the two first buckles 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 to the area between the two first buckles 124.

[0070] The first unlocking member 125 is exposed from the housing 120 so that the user can change the position of the first unlocking member 125 so that the two first buckles 124 abut against the narrow portion 1252, thereby changing the distance between the two first buckles 124. Depending on the different settings of the second elastic member 127, the first unlocking member 125 can move into the housing 120 or out of the housing 120, so that the wide portion 1251 of the first unlocking member 125 leaves the area between the two first buckles 124, and the narrow portion 1252 of the first unlocking member 125 moves to the area between the two first buckles 124. The first elastic member 126 drives the two first buckles 124 to move relative to each other, thereby abutting against the narrow portion 1252, thereby reducing the distance between the two first buckles 124. Since the hook portions 1241 of the two first buckles 124 are arranged in opposite directions, when the distance between the two first buckles 124 becomes smaller, the two hook portions 1241 can be detached from the corresponding mounting portions on the portable ultrasound device 2000, for example, detached from the bayonet of the portable ultrasound device 2000, thereby unlocking the device.

[0071] When the portable ultrasound device 2000 and the shared battery pack 100 need to be detachably fixed, please refer to Figure 5 , 6 8, the user moves the position of the first unlocking member 125 (presses the first unlocking member 125 to move it into the housing 120, and in other embodiments, the first unlocking member 125 may be pulled outward), and the first unlocking member 125 compresses the second elastic member 127, so that the wide portion 1251 located on the inner side moves inward and disengages from the two first buckles 124, and the narrow portion 1252 located on the outer side moves inward to between the two first buckles 124, so that the two first buckles 124 are affected by the first elastic member 126 to press against the narrow portion 1252. At this time, the distance between the two first buckles 124 becomes smaller, and they can be inserted into the corresponding installation part of the portable ultrasound device 2000, such as the bayonet.

[0072] When the user releases the first unlocking member 125, the first unlocking member 125 is reset under the action of the second elastic member 127, so that the wide portion 1251 of the first unlocking member 125 moves back to between the two first buckles 124, so that the two first buckles 124 are stretched outward, and then snap on the corresponding mounting portion of the portable ultrasonic device 2000, for example, snap on the bayonet wall of the portable ultrasonic device 2000, to achieve snap-on fixation. When unlocking is required, the first unlocking member 125 can be pressed again to unlock.

[0073] Of course, the corresponding mounting part of the portable ultrasonic device 2000 can also be directly pressed against the two first buckles 124, so that the first buckles 124 apply pressure to the first unlocking member 125, overcome the pressure of the second elastic member 127 on the first unlocking member 125, move the first unlocking member 125, and move the narrow portion 1252 between the two first buckles 124, thereby changing the distance between the two first buckles 124. When the first buckle 124 is inserted into the corresponding mounting part of the portable ultrasonic device 2000, such as the bayonet, the first buckle 124 is released, and the second elastic member 127 will cause the first unlocking member 125 to reset, so that the two first buckles 124 are reopened and the portable ultrasonic device 2000 is buckled.

[0074] An inclined guide surface may be provided between the wide portion 1251 and the narrow portion 1252 of the first unlocking member 125, so that the wide portion 1251 and the narrow portion 1252 can smoothly move between the two first buckles 124. The first elastic member 126 and the second elastic member 127 (the same applies to other elastic members described below) may be springs but are not limited to them. The first buckle 124 may also be controlled in other forms, for example, the first buckle 124 may be an integral structure with the first unlocking member 125 or the two may be transmission-connected.

[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 provided on the first unlocking member 125 and is used to fix the first unlocking member 125 in the locking position. Specifically, the first unlocking member 125 has a matching portion, such as a limiting opening. The auxiliary locking member 1281 can be assembled to the matching portion, such as inserted into the limiting opening, to lock the first unlocking member 125, and block the first unlocking member 125 from moving from the locking position to the unlocking position, so as to prevent the portable ultrasonic device 2000 and the shared battery pack 100 from being accidentally unlocked during the carrying process (such as carrying in the hand), thereby causing damage to the device. The auxiliary locking elastic member 1282 is installed on the auxiliary locking member 1281, and the auxiliary locking elastic member 1282 gives the auxiliary locking member 1281 an elastic pre-tightening force, so that the auxiliary locking member 1281 remains in the position of locking the first unlocking member 125. The auxiliary locking member 1281 is movably mounted on the housing 120 so that the elastic preload of the auxiliary locking elastic member 1282 can be overcome by external force, thereby moving the position of the auxiliary locking member 1281, unlocking the first unlocking member 125, and further enabling the first unlocking member 125 to be used to unlock the first buckle 124.

[0076] To facilitate locking and unlocking of the portable ultrasound device 2000 and the shared battery pack 100, please refer to Figure 5 and 6In one embodiment, the first buckle 124 extends from the top wall of the housing 120, and the 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 port 129, and the first unlocking member 125 is arranged in the unlocking port 129. When necessary, the unlocking port 129 can also serve as a second mounting portion for the shared battery pack 100 to be locked by the trolley 200, for example, in conjunction with the second buckle to be mentioned later, the shared battery pack 100 is fixed to the trolley 200. The user can conveniently install the portable ultrasound device 2000 on 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 to remove the portable ultrasound device 2000.

[0077] Furthermore, the charging connector 131 and the discharging connector 132 can be connected to the portable ultrasound device 2000 and / or the trolley 200 in a wired or wireless manner. Figure 5 and 6 In one embodiment, it also includes at least one first magnetic socket 133, the first magnetic socket 133 has a first magnetic part that is convenient for attracting the portable ultrasound device 2000 and / or the trolley 200, and the charging connector 131 and the discharging connector 132 are arranged in the same or different first magnetic sockets 133 to realize power supply to the portable ultrasound device 2000 and charging of the battery 110.

[0078] The first magnetic part can adsorb the portable ultrasonic device 2000 and / or the trolley 200 within a certain range. As long as the portable ultrasonic device 2000 and / or the trolley 200 are within the range, they can be automatically attracted to the docking position by the first magnetic socket 133. Of course, the portable ultrasonic device 2000 and / or the trolley 200 may be provided with a structure that magnetically cooperates with the first magnetic part. The first magnetic socket 133 may have a rigid wire, which stands upright and can swing slightly. When the portable ultrasonic device 2000 and / or the trolley 200 are assembled in place, the wire is automatically attracted to the connector of the portable ultrasonic device 2000 and / or the trolley 200 under the action of suction, thereby realizing automatic docking.

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