[0029] In order to make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved more clearly, the technical solutions of the embodiments of this application will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of this application.

[0030] Embodiment 1:

[0031] like Figure 1 As shown, it is a schematic structural diagram of the outdoor work vehicle 400 in Embodiment 1 of the present disclosure.

[0032] The outdoor work vehicle 400 includes: a seat 110, a frame, a walking mechanism 230 and an operating mechanism 240. In this embodiment, the outdoor work vehicle 400 is exemplarily a riding lawn mower, and of course the outdoor work vehicle 400 may also be a snow sweeper, a cleaning machine, a tiller, a wood splitter, a forklift, a walk-behind lawn mower, a standing lawn mower, a seed drill and other multi-purpose vehicles.

[0033] The seat 110 is for users to sit on, and the frame is used to load the seat 110, the operating mechanism 240 and the walking mechanism 230; the walking mechanism 230 is used to drive the outdoor working vehicle 400 to move, and includes at least two driving wheels 2711, and each driving wheel 2711 corresponds to a walking motor 271 to drive, so as to realize the straight-moving, reverse, turning, zero-turn and other motion control of the whole vehicle; the operating mechanism 240 is used for operation. In this embodiment, the operating mechanism 240 includes a cutting knife 2811 for mowing. The outdoor working vehicle 400 has at least one cutting knife 2811, and each cutting knife 2811 corresponds to a working motor 281 to drive.

[0034] The outdoor working vehicle 400 further includes an operating component for receiving user operations to control the operation of the travel motor 271 and the working motor 281. Figure 1 As shown, the operating assembly includes a left operating handle 251 and a right operating handle 252, the left operating handle 251 controls the operation of the left travel motor, and the right operating handle 252 controls the operation of the right travel motor; the operating assembly may also include a cutter switch to control the operation of the cutter 2811, and the operation of the cutter 2811 includes the start and stop, speed, and direction of each cutter. It can be understood that the number of the working motors 281 and the working motor controllers 1830 matches the number of the cutters 2811.

[0035] As an example, Figure 1 As shown, an input unit 421 is arranged in front of the seat 110 of the outdoor work vehicle 400. The input unit 421 is exemplarily an electronic password lock, suitable for the user to input password information to be verified; in other embodiments, the input unit 421 can also be a fingerprint lock, a voiceprint lock, an NFC lock or a camera, and the electronic password lock is arranged facing the seat 110.

[0036] like Figure 4-9 As shown, the outdoor working vehicle 400 is controlled by a control system 410 to perform walking and / or working. Figure 5-7 As shown, the control system 410 includes: a vehicle controller 1810 (VCU), a travel motor controller, an operating motor controller and a battery management system 2942; the travel motor 271 for driving the travel mechanism 230 is controlled by the travel motor controller, and the operating motor 281 for driving the operating mechanism 240 is controlled by the operating motor controller. More specifically, as Figure 6As shown, the travel motor controller includes a left travel controller 1820 connected to and controlling the left travel motor 271, and a right travel controller 1820 connected to and controlling the right travel motor 271; the working motor controller 1830 includes a left cutter controller 1830 connected to and controlling the left cutter motor 281, and a right cutter controller 1830 connected to and controlling the right cutter motor 281. The left travel controller 1820 is communicatively connected to the sensor on the left operating handle 251 and the left travel motor 271, and the right travel controller 1820 is communicatively connected to the sensor on the right operating handle 252 and the right travel motor 271, so as to receive the control signal of the user's operation output for the left travel motor and / or the right travel motor, and the left driving wheel 2711 and the right driving wheel 2711 can be controlled through the left operating handle 251 and the right operating handle 252, so that the outdoor working vehicle 400 can walk in a desired manner.

[0037] The outdoor work vehicle 400 includes a power supply device, which includes a battery 2941 and a battery management system 2942. As an example, the battery 2941 can be a lithium-ion battery 2941, a lead-acid battery 2941, a nickel-metal hydride battery 2941, or other types of power batteries 2941. The battery management system 2942 is used to manage the charging and discharging of the battery 2941, and the battery 2941 supplies power to the electrical equipment on the outdoor work vehicle 400, and the electrical equipment includes various controllers and motors.

[0038] like Figure 1-9 As shown, the vehicle controller 1810 is respectively connected to the electronic password lock, the travel motor controller 1820, the working motor controller 1830 and the battery management system 2942. The vehicle controller 1810 is integrated with an unlock detection unit 422, and the information to be verified input through the electronic password lock keyboard is directly transmitted to the unlock detection unit 422 on the vehicle controller 1810. The unlock detection unit 422 is a part of the control circuit on the vehicle controller 1810, which includes a memory module and a processor module. The memory module stores preset unlock information, and the processor module can determine whether the input information to be verified matches the preset unlock information, and send an unlock signal to the travel motor controller 1820 and / or the working motor controller 1830 in the case of matching, so as to activate the travel motor and / or the working motor.

[0039] Among them, the memory module stores multiple passwords, such as password 1 corresponding to only opening the walking function of the outdoor work vehicle 400, and password 2 corresponding to opening the walking function and the working function of the outdoor work vehicle 400; in a family scenario, if the father and mother are not at home, and only the daughter is at home, and suddenly encounters bad weather such as heavy rain, the father tells the daughter password 1 through the mobile phone, and the daughter can unlock the walking function of the outdoor work vehicle 400 according to password 1 and use it to drive the outdoor work vehicle 400 into the warehouse. Since password 1 does not unlock the use authority of the mowing function, it can prevent the daughter from operating the mower in the process of driving the outdoor work vehicle 400 into the warehouse, avoiding certain dangers and improving the flexibility of use.

[0040] An electronic password lock is a lock that uses circuits and microprocessors to control the switch of a lock. Users can enter a numeric password through the keyboard or touch the screen to operate. This type of lock usually has an anti-dismantling function and a safety locking mechanism when an incorrect password is entered. The electronic password lock includes main components such as a power supply, a keyboard / touch screen, a microprocessor / control unit, a lock body mechanical structure, a memory unit, etc. In another embodiment, the unlock detection unit 422 (UDU) can also be set on the microprocessor / control unit on the electronic password lock. The microprocessor / control unit on the electronic password lock is at least communicated with one of the vehicle controller 1810 (VCU), the motor controller, and the battery 2941 management system on the outdoor work vehicle 400. The unlock detection unit 422 sends different unlock signals to the controller that is communicated with it according to different passwords, and finally selectively activates the travel motor and / or the working motor. The unlock detection unit 422 and the input unit 421 together constitute an unlock component 420 that controls the unlocking of the outdoor work vehicle. As Figure 6 and Figure 7 As shown, the left walking controller, right walking controller, left mowing controller, right mowing controller, vehicle controller 1810, and battery management system 2942 on the outdoor work vehicle 400 can be partially combined or separately arranged. Each controller is provided with a control circuit with corresponding functions, and the controllers are selectively communicated with each other.

[0041] The startup process of the outdoor work vehicle 400 of this embodiment is as follows: S1. The user presses the start switch, the main circuits of the battery management system 2942, each motor controller module, and the signal module are powered on and the vehicle controller 1810 (VCU) is activated; S2. The user enters the password through the electronic password lock, and the unlocking detection unit 422 determines whether the password is correct, and selects the usage permission corresponding to the password when the password is correct, and sends an unlocking signal under the corresponding permission to the walking motor controller 1820 and / or the working motor controller 1830 to activate the walking 271 and / or the working motor 281, and enters the locked state when the input password error reaches a preset threshold; S3. The user actuates the operating component to perform corresponding walking and / or working.

[0042] Since the working vehicle will be equipped with working motors and working tools (such as cutting knives), the outdoor working vehicle 400 will be dangerous when starting. For safety reasons, in order to avoid user misoperation and misstart, the user needs to meet at least two action signals before operating the outdoor working vehicle 400 to start the outdoor working vehicle 400. In this embodiment, an electronic password lock is used instead of a physical key as protection before the outdoor working vehicle 400 is started, thereby solving the problems of the cost of the matching circuit of the physical key switch, the complexity of the wiring harness, the easy jumping during bumps leading to shutdown, and the easy loss.
