[0082] The technical solutions of the utility model will be described clearly and completely in combination with the drawings. Obviously, the described embodiments are part of the embodiments of the utility model and not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skilled in the art without creative labor belong to the protection scope of the utility model.

[0083] Referring to Figure 1 The electric walking vehicle 100 at least includes a main body 10, wheels 11, an electric motor 12 and a circuit unit. The main body 10 at least includes a seat 10a for a user to sit on and a first battery mounting portion 10b. The wheels 11 are rotatably supported at the bottom of the main body 10. The electric motor 12 is configured to apply torque to at least one wheel 11 to drive the wheel 11 to rotate. The circuit unit is configured to electrically connect at least a battery pack 300 attached to the battery mounting portion 10b and the electric motor 12. Thus, the at least one wheel 11 is driven by the power provided from the battery pack 300. The user can sit on the seat 10a and operate the joystick to control the electric walking vehicle 100, such as turning on, going forward, going backward, turning, etc. In particular, the battery pack 300 is configured in the first battery mounting portion 10b in a detachable manner. The first battery mounting portion 10b includes a first coupler 13a adapted to mechanically and electrically connect with a power output port of the battery pack 300.

[0084] The battery pack 300 is initially designed as a power source of a portable medical instrument 200. The portable medical instrument 200 is configured to be used by power driving. The portable medical instrument 200 has a second coupler 13b configured the same as the first coupler 13a. Specifically, referring to Figure 2 The portable atomizer 200c is taken as an example to illustrate that the battery pack 300 is initially designed as a power source of the portable medical instrument 200. The portable atomizer 200c needs to be driven by power to perform atomization work. The portable atomizer 200c includes a housing 20 and a second battery mounting portion 20b. The second battery mounting portion 20b includes a second coupler 13b adapted to mechanically and electrically connect with the power output port of the battery pack 300. The second coupler 13b is configured the same as the first coupler 13a. The detailed configuration is specifically referred to below.

[0085] When the atomization operation is needed, the battery pack 300 is installed into the second battery mounting portion 20b, the power output port of the battery pack is mechanically and electrically connected with the second coupler 13b, the starting switch of the portable atomizer 200c is turned on, and the battery pack 300 provides driving power to the operation element, such as the compressor, of the portable atomizer 200c through the second coupler 13b mechanically and electrically connected therewith.

[0086] Further, referring to Figure 3 , the first and second couplers (13a, 13b) comprise:

[0087] a coupler positive and negative power terminal (130, 131) configured to be adapted to be electrically connected to the corresponding battery pack positive and negative power terminal (301, 302) of the battery pack 300;

[0088] at least one communication terminal 132 electrically connected to the device side controller of the electrically powered walking vehicle 100 or the portable medical instrument 200 and configured to be adapted to be electrically connected to at least one corresponding signal terminal 303 of the battery pack 300 for transmitting information from the battery pack 300 to the device side controller for controlling the discharge of the battery pack 300.

[0089] Further, referring to Figure 3 , the battery pack 300 comprises:

[0090] a battery pack positive and negative power terminal (301, 302), a signal terminal 303 and a power side controller 304;

[0091] The power side controller 304 is configured to transmit first information, such as identification information, to the device side controller and receive first response information from the device side controller within a predetermined time period; when the first response information is received within the predetermined time period, communication with the device side controller is established; when the first response information is not received within the predetermined time period, communication with the device side controller is not established.

[0092] The battery pack 300 can transmit first information, such as identification information, preferably a multi-byte message, to the device, such as the electrically powered walking vehicle 100 or the portable medical instrument 200 or the charger, connected therewith, which can be configured to receive the first message and respond to the power side controller 304 according to the message, and the power side controller 304 periodically queries the device side controller to verify whether the battery pack is connected to the device and the proper function (such as charging function, discharging function, etc.).

[0093] For example, the power supply side controller 304 transmits a plurality of messages to the device side controller within three communication cycles to initiate and expect to establish communication with the device. If the power supply side controller 304 fails to receive an expected response or valid message from the device side controller during this time period, the power supply side controller 304 turns off the charge and discharge control module and enters a sleep mode.

[0094] When in the sleep mode, the power consumption of the battery pack 300 is minimized, and in addition to the power consumption of the battery pack 300 being minimized, the sleep mode is also safer. For example, when in the sleep mode, the battery pack 300 cannot provide any significant power to an external device or the positive and negative power terminals of the battery pack. In this way, the risk of a short circuit of the positive and negative power terminals that can cause a fire or similar safety issue is eliminated or significantly reduced.

[0095] It is noted that the battery pack 300 only powers the discharge to drive the electrically powered mobility vehicle 100 and the portable medical instrument 200 to operate if and only if the power supply side controller 304 establishes communication with the device side controller through the signal terminal 303.

[0096] In this way, the battery pack 300 can identify the device connected thereto as the electrically powered mobility vehicle 100 or the portable medical instrument 200 or the charger and control whether to allow the electrically powered mobility vehicle 100 or the portable medical instrument 200 or the charger connected thereto to access the charge / discharge circuit thereof.

[0097] In particular, the power supply side controller 304 includes a processor, a memory having program data stored therein. The power supply side controller 304 can be configured to communicate with a device (e.g., a battery charger, an electrically powered mobility vehicle 100, a portable medical instrument 200, etc.), measure voltages of individual cells within the battery pack 300, measure a discharge current of the battery pack, control a plurality of field effect transistor ("FET") switches, measure a temperature of the battery pack, and monitor a number of charge or discharge cycles.

[0098] In addition, the power supply side controller 304 can also store charging and / or discharging operation parameters and the above-mentioned identity information, and the battery pack 300 can provide the charging and / or discharging operation parameters to the charger, the electrically powered mobility vehicle 100 or the portable medical instrument 200, wherein the operation parameters include, for example, a rated voltage, a rated capacity, a rated current, a charge current limit, a discharge current limit, a remaining power amount, a discharge cutoff voltage, etc. of the battery pack.

[0099] Further, referring to FIG. 1, the battery pack 300 also includes a discharge control module 305; Figure 4

[0100] The battery pack 300 is configured to: ​

[0101] communication with the device-side controller is established through the electrical connection of the signal terminal 303 with the communication terminal 132;

[0102] identifying the electrically powered mobility vehicle 100 or the portable medical instrument 200 to which the battery pack 300 is connected;

[0103] transmitting the second information to the device-side controller of the electrically powered mobility vehicle 100 or the portable medical instrument 200 to which the battery pack 300 is connected, and

[0104] controlling the discharge control module 305 based on the communication with the electrically powered mobility vehicle 100 or the portable medical instrument 200 using the power source-side controller 304.

[0105] The second information can be working state data information of the battery pack 300, such as real-time voltage data information, current data information, temperature data information, etc. The discharge control module 305 comprises at least one FET configured as a switch to control the discharge current from the battery pack. If the FET is in “on”, the battery pack can be discharged. If the FET is in “off”, the battery pack is not discharged. The discharge control module 305 is controlled by the power source-side controller 304.

[0106] Further, the electrically powered mobility vehicle 100 or the portable medical instrument 200 is configured to:

[0107] receive the second information when the first coupler 13a or the second coupler 13b connects the battery pack 300 and has established communication with the battery pack 300;

[0108] generate second response information in response to the second information, and

[0109] transmit the second response information to the battery pack 300; wherein,

[0110] receive power from the battery pack 300 when the electrically powered mobility vehicle 100 or the portable medical instrument 200 has established communication with the battery pack 300 and the discharge control module 305 is on; and / or,

[0111] turn off the discharge control module 305 when the power source-side controller 304 does not receive the second response information from the device-side controller within a predetermined time period.

[0112] For example, when the battery pack 300 is installed in the battery mounting portion, the power output port of the battery pack 300 is mechanically and electrically connected with the first coupler 13a or the second coupler 13b, the identity of both is identified, and communication is established, the battery pack 300 continues to transmit second information, such as working state data information, to the electrically powered scooter 100 or the portable medical instrument 200, turns on the operation start switch of the electrically powered scooter 100 or the portable medical instrument 200, and in response to the second information, the device-side controller generates second response information, while the discharge control module 305 is turned on, the electrically powered scooter 100 or the portable medical instrument 200 receives power from the battery pack 300.

[0113] When the battery pack 300 is installed in the battery mounting portion, the power output port of the battery pack 300 is mechanically and electrically connected with the first coupler 13a or the second coupler 13b, the identity of both is identified, and communication is established, the battery pack 300 continues to transmit second information, such as working state data information, to the electrically powered scooter 100 or the portable medical instrument 200, and the electrically powered scooter 100 or the portable medical instrument 200 is always in an unpowered state, the power-side controller 304 does not receive the second response information from the device-side controller within a predetermined time period, and the discharge control module 305 is turned off and enters a sleep mode.

[0114] When the operation start switch of the electrically powered scooter 100 or the portable medical instrument 200 is operated to be turned on at a certain moment, the power-side controller 304 of the battery pack 300 is activated to be woken up and continues to transmit second information to the electrically powered scooter 100 or the portable medical instrument 200.

[0115] In addition, in the case where the battery pack 300 is configured with the discharge control module 305, the electrically powered scooter 100 or the portable medical instrument 200 communicates with the battery pack 300 and can also adjust other operations based on the operating parameters of the battery pack 300. For example, when the voltage of the battery pack 300 drops below a predetermined discharge cutoff voltage, the battery pack 300 terminates the discharge current and enters a sleep mode regardless of whether communication with the device-side controller is established. For another example, if the voltage of one of the battery cells of the battery pack 300 drops below a predetermined low-voltage limit, the battery pack 300 also turns off the discharge control module 305 to terminate the discharge current and enter a sleep mode regardless of whether communication with the device controller is established. For yet another example, if the temperature of the battery pack 300 reaches a predetermined temperature limit, the battery pack 300 also turns off the discharge control module 305 to terminate the discharge current and enter a sleep mode regardless of whether communication with the device controller is established.

[0116] Referring to Figure 5 As shown in FIG. 8, in another embodiment of the battery pack, the battery pack 300 is configured to:

[0117] communication with the device-side controller is established through the electrical connection of the signal terminal 303 with the communication terminal 132;

[0118] identifying the electrically powered mobility vehicle 100 or the portable medical instrument 200 to which the battery pack 300 is connected;

[0119] transmitting the second information to the device-side controller of the electrically powered mobility vehicle 100 or the portable medical instrument 200 to which the battery pack 300 is connected, and

[0120] controlling the device-side discharge switch S of the electrically powered mobility vehicle 100 or the portable medical instrument 200 based on the communication with the electrically powered mobility vehicle 100 or the portable medical instrument 200 using the device-side controller.

[0121] At this time, the discharge control module described above is not provided inside the battery pack 300, but the device-side discharge switch S is configured at the device side.

[0122] The device-side discharge switch S is preferably a FET. If the FET is in "on", the battery pack is connected to the discharge circuit at the device side. If the FET is in "off", the battery pack is disconnected from the discharge circuit at the device side. The device-side discharge switch S is controlled by the device-side controller.

[0123] Further, the electrically powered mobility vehicle 100 or the portable medical instrument 200 is configured to:

[0135] Further, referring to Figure 7 , the battery pack 300 includes a first battery pack 300a and a second battery pack 300b, and each of the first battery pack 300a and the second battery pack 300b is initially designed as a power supply of the portable medical instrument 200.

[0136] More specifically, a latch structure and an actuator are provided between the battery pack 300 and the battery mounting portion, the latch structure is adapted to latch connect the battery pack 300 to the battery mounting portion, and the actuator is located on the battery pack 300 or the main body 10 and is operable to switch the latch structure between the engaged state and the disconnected state.

[0137] Referring to Figure 8 and Figure 9 , the battery pack 300 has a latch 307 which is latched connected with a lock key 307S provided on the electrically powered scooter 100 or the portable medical instrument 200 side. Further, referring to Figure 8 and Figure 9 , the battery pack 300 includes an actuator 306, operating the actuator 306 actuates an arm 308, so that the latch 307 connected with the arm 308 swings to disengage the latch 307 from the lock key 307S to unlock, at this time, the battery pack 300 can be operated to be taken out, in addition, the periphery of the latch 307 is connected with a torsional spring 309 for resetting.

[0138] In addition, since the battery pack 300 is initially designed as a power supply of the portable medical instrument 200. There is a possibility that the working voltage of the portable medical instrument 200 is different from that of the electrically powered scooter 100, which leads to that the battery pack 300 cannot be applicable to the electrically powered scooter 100, therefore, the electrically powered scooter 100 is configured with a voltage conversion circuit.

[0139] Referring specifically to Figure 10 , the electrically powered scooter 100 further comprises:

[0140] a voltage conversion circuit configured inside the main body 10 and electrically connected to the first coupler 13a and the electric motor 12, respectively, for converting the voltage from the battery pack 300 into the operating voltage of the electric motor 12. More preferably, the voltage conversion circuit is preferably a DC / DC boost circuit, considering that the battery pack 300 is originally designed as the power source of the portable medical instrument 200. While the portable medical instrument 200 is considered for portability, the battery pack is designed to be miniaturized, resulting in a lower voltage of the battery pack, such as 12V or 18V or 24V; while the electrically powered walking vehicle 100 is generally bulky, and tends to use a 42V or 56V battery pack as the driving power source, therefore the voltage conversion circuit is preferably a DC / DC boost circuit, so that the power source of the portable medical instrument 200 is compatible with the power source of the electrically powered walking vehicle 100, both of which can share a battery pack, and thus the electrically powered walking vehicle 100 can be sold together with the portable medical instrument 200, reducing the purchase cost of the user.

[0141] Further, referring to Figure 11 The utility model also provides a kind of electrically powered walking vehicle and portable medical instrument combination, it includes:

[0142] Electrically powered walking vehicle 100, including main body 10, wheel 11 placed in the bottom of main body 10 and first electric motor, and the first electric motor is to at least one wheel 11 apply torque, main body 10 defines a first battery mounting portion 10b with first opening, and first battery mounting portion 10b includes first coupler 13a;

[0143] Portable medical instrument 200, including shell 20, controller and operating element placed in the shell, and the shell defines a second battery mounting portion 20b with second opening, and second opening is consistent with the shape and size of first opening, and second battery mounting portion 20b includes second coupler 13b;

[0144] At least one battery pack 300 is configured to be detachably connected to electrically powered walking vehicle 100 and portable medical instrument 200;

[0145] When connected to electrically powered walking vehicle 100, the power output port of battery pack 300 is mechanically and electrically connected with first coupler 13a to close first opening, and is configured to be communicatively connected to electrically powered walking vehicle 100, and battery pack 300 can selectively power first electric motor;

[0146] When connected to portable medical instrument 200, the power output port of battery pack 300 is mechanically and electrically connected with second coupler 13b to close second opening, and is configured to be communicatively connected to portable medical instrument 200, and battery pack 300 can selectively power operating element.

[0147] The battery pack 300 selectively supplies power to the first electric motor or the work element. Details can be referred to the above and shown in Figure 4 、 Figure 5 and Figure 6 , which are not repeated here.

[0148] Further, as mentioned above, the portable medical instrument 200 is designed to be portable, the battery pack tends to be miniaturized, resulting in a lower voltage, such as 12V or 18V or 24V; while the electrically powered walking vehicle 100 is generally bulky, tends to use a 42V or 56V battery pack as a driving power source. When the portable medical instrument 200 needs to share the power source of the electrically powered walking vehicle 100, it is more preferable that the portable medical instrument 200 further comprises a voltage conversion circuit, which is disposed inside the housing and electrically connected to the second coupler 13b and the work element respectively, for converting the voltage from the battery pack 300 into the working voltage of the work element.

[0149] Thus, the nominal working voltage of the portable medical instrument 200 is lower than that of the electrically powered walking vehicle 100.

[0150] Further, the battery pack 300 has a nominal voltage consistent with the nominal working voltage of the electrically powered walking vehicle 100.

[0151] More specifically, the above-mentioned voltage conversion circuit is a DC / DC step-down circuit.

[0152] In addition, the portable medical instrument 200 is preferably a motorized portable medical instrument 200, comprising a second electric motor disposed in the housing, the nominal working voltage of the second electric motor being lower than that of the first electric motor.

[0153] Further, the portable medical instrument 200 comprises a portable oxygen generator 200a, a portable breathing machine 200b, a portable nebulizer 200c, a portable hydrogen generator 200d.

[0154] Further, the combination of the electrically powered walking vehicle and the portable medical instrument further comprises:

[0155] a charger 400, comprising a receiving portion for receiving the battery pack 300, and a charger terminal disposed in the receiving portion, the battery pack 300 being removed from either of the battery mounting portions, i.e. the first battery mounting portion 10b or the second battery mounting portion 20b, and being received in the receiving portion and mechanically and electrically connected with the charger terminal, when being charged away from the electrically powered walking vehicle 100 or the portable medical instrument 200.

[0156] In addition, continuing to refer to Figure 11As shown, the combination of the electrically powered walking vehicle and the portable medical apparatus further comprises an inverter 500.

[0157] The inverter 500 is adapted to be connected with the battery pack 300 in a matching manner to inversely output AC current from the DC current at the power output end of the battery pack 300 for use by the user, for example, by using the battery pack 300 in combination with the inverter 500 to supply power to a conventional AC type electric product with a power cord connected to an AC power source, including a conventional AC type breathing machine, oxygen generator, atomizer, etc.

[0158] Further, the above-mentioned inverter 500 is a bidirectional inverter, that is, at least comprises a bidirectional AC / DC circuit 500a, so that the battery pack 300 can be charged by the inverter 500 and inversely output by the battery pack 300.

[0159] Referring to Figure 12 and Figure 13 As shown, the inverter 500 is a bidirectional inverter, that is, at least comprises a bidirectional AC / DC circuit 500a, which can be combined with a conventional AC type electric product with a power cord, such as a breathing machine, an oxygen generator, an atomizer, etc., to form an emergency backup power supply system scheme.

[0160] Referring to Figure 12 As shown, the input end of the inverter 500 is connected with AC power, and the output end is connected with an AC type electric product with a power cord, such as a breathing machine, an oxygen generator, an atomizer, etc., and specifically taking an AC type atomizer 2000c as an example, the battery pack 300 is connected with the inverter 500, at this time, one way of the connected AC power is supplied to the battery pack 300 for charging through the bidirectional AC / DC circuit 500a, and the other way is bypassed and output directly to supply power to the AC type atomizer 2000c.

[0161] Referring to Figure 13 As shown, the input end of the inverter 500 is disconnected with the AC power, and the battery pack 300 continues to supply power to the AC type atomizer 2000c by inversely outputting through the bidirectional AC / DC circuit 500a, so that the AC type atomizer 2000c can avoid stopping operation due to sudden power failure during atomization operation.
