[0025] The electric cargo box roller shutter can effectively protect the safety of goods during transportation and prevent the goods from being damaged due to bumps during transportation. It has good sealing properties and can effectively isolate the external environment, reducing the loss of goods caused by changes in the external environment.
[0026] In extremely cold weather or places with harsh climatic conditions, the electric cargo box roller shutter may be frozen by ice or stuck by sand and gravel, making it impossible to open normally.
[0027] In view of this, the present disclosure proposes a method, device, medium and product for opening an electric cargo box roller shutter, which continuously increases the input power of the drive motor to continuously improve the driving capacity of the drive motor, and ultimately enables the electric cargo box roller shutter to open smoothly.
[0028] Figure 1 is a flow chart showing a method for opening an electric cargo box roller curtain according to some embodiments of the present disclosure. Figure 1 As shown, the method for opening the electric cargo box roller shutter includes steps 110 to 160.
[0029] In step 110, an instruction to open the electric cargo box roller shutter is obtained.
[0030] The electric cargo box roller shutter is an electric roller shutter mechanism powered by a tubular motor and is mainly used for opening and closing the cargo box.
[0031] In some embodiments, a rotation speed sensor is provided on the tubular motor to detect whether the driving motor is rotating.
[0032] In some embodiments, the command to open the electric cargo box roller shutter can be initiated through the central control in the pickup truck.
[0033] In step 120, based on the electric cargo box roller shutter opening instruction, the drive motor is controlled to perform a rotation action to open the electric cargo box roller shutter.
[0034] In some embodiments, the executing entity is an electric cargo box roller shutter controller, which receives the roller shutter opening command sent by the central control, and then drives the tubular drive motor to rotate, thereby driving the roller shutter body to slide along the roller shutter frame, and then opens the roller shutter body to facilitate the storage and retrieval of goods.
[0035] In step 130 , the rotation speed of the driving motor is detected.
[0036] The purpose of detecting the rotation speed is to know whether the roller shutter body is stuck by sand or gravel, or whether it is frozen by ice. Freezing generally refers to ice freezing the roller shutter body to the roller shutter frame, resulting in the use of normal input power, and the drive motor cannot pull open the roller shutter body. At normal temperature, the roller shutter body is not fixed to the roller shutter frame. By using the first level of input power, the roller shutter body can be moved along the roller shutter frame to store and retrieve goods. The first level of input power is the minimum power set to achieve energy saving. In this embodiment, the pickup truck sets five levels of input power, and the highest level of input power is the fifth level of input power. If the fifth level of input power is used to energize the tubular drive motor, it is necessary to ensure the normal use of the entire vehicle. This is also the standard for setting the value of the fifth level of input power. Of course, the fifth level of input power must be sufficient to open the roller shutter body.
[0037] In step 140 , if the speed of the driving motor is equal to zero, the input power of the driving motor is increased.
[0038] From the above, it can be seen that the speed sensor detects that the motor speed is zero, indicating that the roller shutter body has been stuck on the roller shutter frame by sand or ice, resulting in that although power is input to the drive motor, the motor does not rotate. Therefore, the speed is zero. Once the central control detects that the speed is equal to zero, it triggers the input power increase action. Since the input power is set to five levels, it increases by one level at a time.
[0039] In step 150 , the rotation speed detection action and the input power increase action are repeatedly executed.
[0040] In severe cold weather, a pickup truck is parked on the side of the road. When the owner is storing or retrieving goods from the cargo box, an opening command is issued, and the vehicle system will alternately perform speed detection and input power increase actions. When the first level of input power is used to energize the drive motor, the motor speed is detected to be zero; then the second level of input power is used to energize the drive motor, and the motor speed is still zero; the third level of input power is used to energize the drive motor, and the motor starts to rotate, indicating that the roller shutter body has begun to open. Increasing power according to the level is convenient for saving electricity.
[0041] In step 160, when it is detected that the rotation speed of the drive motor is greater than zero, and the time for which the drive motor rotates uninterruptedly is equal to the time threshold, the opening of the electric cargo box roller shutter that is stuck by sand or frozen by ice is completed.
[0042] Experiments have shown that the time threshold is set at 6 seconds, and the roller shutter body can be opened to a certain extent, that is, to a degree that does not affect the owner's storage and retrieval of goods. Because it may snow in severe cold weather, it only needs to be opened to the necessary extent, which is convenient for storage and retrieval and prevents the goods in the cargo box from being affected by the external environment.
[0043] In some embodiments, in order to enhance the user's driving experience, a voice prompt system is also set up. When the roller blind body is opened, the voice prompt system prompts the owner that the roller blind body has been successfully opened.
