Description

Technical Field

[0001] This invention relates to the field of engineering machinery technology, and in particular to a control system and method for assisted overturning of excavators. Background Technology

[0002] In the current field of construction machinery, the armrest boxes used are still of two types: fixed and non-rotatable, and mechanically manually rotated. The former occupies a large amount of space when getting on and off the vehicle, affecting the overall comfort of the vehicle; the latter still requires manual operation, and there is a problem that the actual state of the armrest box is different from the required state when getting on, getting off, or starting the vehicle, requiring manual lifting and lowering, which is inconvenient.

[0003] Specifically, the non-flipable armrest box only allows the safety handle to be raised and lowered, while the box body occupies the space for getting in and out of the vehicle, affecting the driver's entry and exit and posing a certain safety hazard. The mechanically operated manual flip armrest box still requires manual operation and cannot automatically flip according to the current state. It needs to be manually adjusted when getting into the car or starting the engine, which affects the driving experience. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a control system and method for an armrest box that can automatically flip according to actual needs.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An armrest box auxiliary tilting control system includes an electronic monitor, a contact switch, a seat sensor, a key switch, a tilt switch, an infrared sensor, a pressure sensor, a tilt sensor, a controller, a lifting device, and an armrest box; The electronic monitor is used to set the automatic flipping function to be turned on / off, set the flipping angle of the armrest box, and communicate with the controller via CAN bus; The contact switch is installed on the driver's side door and is used to detect the open / closed status of the door; The seat sensor can detect whether there is someone in the driver's seat; The key switch is connected to the controller via a hardwire and is used to collect start / stop signals; The flip switch is installed in the driver's cab and is used to control the flipping of the armrest box; The infrared sensor is installed on the armrest box to detect whether there are obstacles in the path of the armrest box when it is raised / lowered; The pressure sensor is used to collect LS pressure to determine whether the vehicle is in operation. The tilt sensor is installed on the armrest box and is used to detect the tilt angle of the armrest box; The controller is used to collect data and issue commands; The lifting device is used to control the raising and lowering of the armrest box; The armrest box is used to control the on / off state of the lifting device via raised and lowered position signals.

[0006] Furthermore, a method for assisting in the tilting control of the armrest box includes the following steps: Step 1: The controller checks whether the automatic tilt function is enabled. If it is not enabled, manual tilt is still used. If the tilt function is enabled, the controller determines whether there is someone in the driver's seat based on the seat sensor. If there is no one in the driver's seat, when the door is detected to be open, if the armrest box is not raised, the controller controls the armrest box to lift automatically. Step 2: If the seat sensor detects that there is someone in the driver's seat, and if the flip switch does not move and the engine is not running, then check if the armrest box has been lifted. If the armrest box has not been lifted and the infrared sensor finds that there is no obstruction in the flipping path, then the controller controls the armrest box to lift automatically. Step 3: If the seat sensor detects that there is someone in the driver's seat, and if the flip switch does not move and the engine is already running, the controller will check whether it has received an engine shutdown signal. If an engine shutdown signal is detected, the controller will check whether the armrest box has been lifted. If the armrest box has not been lifted and the infrared sensor finds that the flip path is unobstructed, the controller will control the armrest box to lift automatically. Step 4: If the seat sensor detects that there is someone in the driver's seat, and the flip switch is activated, the infrared sensor will detect whether there are any obstacles in the flipping path. If there are no obstacles, the armrest box will flip.

[0007] Furthermore, the specific details of step one are as follows: 1) The controller checks whether the automatic flip function is enabled. If it is not enabled, the flip control is stopped and manual flipping is used. 2) If the flip function is activated, the seat sensor will determine whether there is anyone in the driver's seat. If no one is in the driver's seat, the contact switch will determine whether the door is open. If the door is not open, the flip control will be terminated. 3) If the door is already open, the controller determines the status of the armrest box based on the raised or lowered position signal. If the armrest box is already raised, the flip control ends. 4) If the armrest box is not raised, the controller will automatically raise the armrest box.

[0008] Furthermore, step two is detailed as follows: The controller checks whether the automatic flip function is enabled. If it is not enabled, it ends the flip control and uses manual flipping. If the flip function is activated, the seat sensor will determine whether there is someone in the driver's seat. If someone is in the driver's seat, the sensor will determine whether the flip switch has been operated. If the flip switch has not been operated, the key switch will determine whether the engine is running. If the engine is not running, the controller determines the status of the armrest box based on the raised and lowered position signals. If the armrest box has been raised, the flip control ends. If the armrest box is not raised, the infrared sensor will determine whether there is an obstacle in the path of the armrest box. If there is an obstacle, the flip control will end. If the infrared sensor does not detect an obstacle, the controller will automatically lift the armrest box.

[0009] Furthermore, step three is detailed below: The controller checks whether the automatic flip function is enabled. If it is not enabled, it ends the flip control and uses manual flipping. If the flip function is activated, the seat sensor will determine whether there is someone in the driver's seat. If someone is in the driver's seat, the sensor will determine whether the flip switch has been operated. If the flip switch has not been operated, the key switch will determine whether the engine is running. If the engine is running, determine if there is an engine shutdown signal. If there is no engine shutdown signal, end the rollover control. If there is an engine shutdown signal, the controller determines the status of the armrest box based on the raised or lowered position signal. If the armrest box has been raised, the flip control ends. If the armrest box is not raised, the infrared sensor will determine whether there is an obstacle in the path of the armrest box. If there is an obstacle, the flip control will end. If the infrared sensor does not detect an obstacle, the controller will automatically lift the armrest box.

[0010] Furthermore, step four is detailed below: The controller checks whether the automatic flip function is enabled. If it is not enabled, it ends the flip control and uses manual flipping. If the flip function is activated, the seat sensor determines whether there is someone in the driver's seat. If someone is there, it determines whether the flip switch has been operated. If the flip switch has been operated, the infrared sensor determines whether there is an obstacle in the path of the armrest box being lifted. If there is an obstacle, the flip control is terminated. If the infrared sensor does not detect an obstacle, the controller will automatically flip the armrest box.

[0011] The system and method of the present invention can automatically rotate the armrest box according to the driver's required state, thereby improving the driver's comfort and enhancing human-machine safety. Attached Figure Description

It should be understood that the embodiments and specific features in the embodiments are detailed descriptions of the technical solution of the present application, rather than limitations thereof. In the absence of conflict, the embodiments and technical features in the embodiments can be combined with each other.

[0014] In this article, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0015] like Figure 1 As shown, this invention discloses an armrest box auxiliary tilting control system. This control system includes an electronic monitor 1, a contact switch 2, a seat sensor 3, a key switch 4, a tilt switch 5, an infrared sensor 6, a pressure sensor 7, a tilt sensor 8, a controller 9, an electric telescopic rod 10, and an armrest box. 11 Electronic monitor 1 is used to set the automatic tilt function to be turned on / off, and to set the tilt angle of the armrest box. It communicates with controller 9 via CAN bus. Contact switch 2 is installed on the driver's side door to detect the opening / closing of the door. Seat sensor 3 can detect whether there is someone in the driver's seat. Key switch 4 is connected to controller 9 via hard wire to collect start / stop signals. Tilting switch 5 is installed in the driver's cab to control the tilt of the armrest box. Infrared sensor 6 is installed on the armrest box to detect whether there are obstacles in the lifting / lowering path of the armrest box, so as to avoid collision with obstacles during the lifting and lowering process. Pressure sensor 7 is used to collect LS pressure to determine whether the whole vehicle is in working condition. Tilt sensor 8 is installed on the armrest box to detect the tilt angle of the armrest box, so that users can set the tilt angle according to their own habits. Controller 9 is used to collect data and issue commands. Electric telescopic rod 10 is used to control the lifting and lowering of the armrest box. The armrest box uses the lifting and lowering position signals to control the on / off of electric telescopic operation, ensuring human and machine safety.

[0016] like Figure 2 As shown, the control method of the present invention is as follows: First, the controller 9 checks whether the automatic flip function is enabled based on the instrument settings. If it is not enabled, manual flipping is still used. If the flip function is enabled, the controller 9 determines whether there is someone in the driver's seat based on the seat sensor 3. If there is no one in the driver's seat, when the door is detected to be open, if the armrest box is not raised, the controller 9 controls the armrest box to be raised automatically to facilitate the driver to get into the vehicle.

[0017] The specific steps are as follows: 1) Controller 9 detects whether the automatic flip function is enabled. If it is not enabled, the flip control is ended and manual flipping is used. 2) If the flip function is activated, the seat sensor 3 determines whether there is anyone in the driver's seat. If no one is in the driver's seat, the contact switch 2 determines whether the door is open. If the door is not open, the flip control ends. 3) If the door is already open, the controller 9 determines the status of the armrest box based on the position signal of the armrest box being raised or lowered. If the armrest box is already raised, the flip control ends. 4) If the armrest box is not raised, the controller 9 will control the armrest box to be raised automatically.

[0018] 2. If the seat sensor 3 detects that there is someone in the driver's seat, and if the flip switch 5 does not move and the engine is not running, then the controller 9 will detect whether the armrest box has been lifted. If the armrest box has not been lifted and the infrared sensor 6 detects that there is no obstruction in the flipping path (to avoid collision with people when the armrest box is flipped), then the controller 9 will control the armrest box to be lifted automatically to facilitate the driver to start the engine.

[0019] The specific steps are as follows: 5) Controller 9 detects whether the automatic flip function is enabled. If it is not enabled, the flip control ends and manual flipping is used. 6) If the flip function is activated, the seat sensor 3 determines whether there is someone in the driver's seat. If there is someone, it determines whether the flip switch 5 is operated. If the flip switch 5 is not operated, the key switch 4 determines whether the engine is running. 7) If the engine is not running, the controller 9 determines the status of the armrest box based on the lifting and lowering position signals. If the armrest box has been lifted, the flipping control ends. 8) If the armrest box is not raised, the infrared sensor 6 will determine whether there is an obstacle in the path of the armrest box. If there is an obstacle, the flip control will end. 9) If the infrared sensor 6 does not detect an obstacle, the controller 9 will control the armrest box to lift automatically.

[0020] 3. If the seat sensor 3 detects that there is someone in the driver's seat, and if the flip switch 5 does not move and the engine is already running, the controller 9 will check whether it has received an engine shutdown signal. If the engine shutdown signal is detected, the controller will check whether the armrest box has been lifted. If the armrest box has not been lifted and the infrared sensor 6 finds that the flipping path is unobstructed (to avoid collision with people when the armrest box flips), the controller 9 will control the armrest box to lift automatically to facilitate the driver getting out of the vehicle.

[0021] The specific steps are as follows: 6) Controller 9 detects whether the automatic flip function is enabled. If it is not enabled, the flip control ends and manual flipping is used. 7) If the flip function is activated, the seat sensor 3 determines whether there is someone in the driver's seat. If there is someone, it determines whether the flip switch 5 is operated. If the flip switch 5 is not operated, it determines whether the engine is running through the key switch 4. 8) If the engine is running, determine if there is an engine shutdown signal. If there is no engine shutdown signal, end the rollover control. 9) If there is an engine shutdown signal, the controller 9 determines the status of the armrest box based on the position signals of the armrest box being raised or lowered. If the armrest box has been raised, the flip control ends. 10) If the armrest box is not raised, the infrared sensor 6 will determine whether there is an obstacle in the path of the armrest box being raised. If there is an obstacle, the flip control will end. 11) If the infrared sensor 6 does not detect an obstacle, the controller 9 will control the armrest box to lift automatically.

[0022] IV. If seat sensor 3 detects someone in the driver's seat, and if the flip switch 5 is activated, infrared sensor 6 will detect any obstacles in the flipping path (to prevent collisions with people when the armrest box flips). If there are no obstacles, the armrest box will flip, allowing the driver to easily lift / lower it at any time. 11 The specific steps are as follows: 5) Controller 9 detects whether the automatic flip function is enabled. If it is not enabled, the flip control ends and manual flipping is used. 6) If the flip function is activated, the seat sensor 3 determines whether there is someone in the driver's seat. If there is someone, it determines whether the flip switch 5 is operated. If the flip switch 5 is operated, the infrared sensor 6 determines whether there is an obstacle in the path of the armrest box being lifted. If there is an obstacle, the flip control is terminated. 7) If the infrared sensor 6 does not detect an obstacle, the controller 9 will control the armrest box to automatically flip.

[0023] The tilt angle of the armrest box can be collected by the tilt sensor 8 and personalized in the electronic monitor 1 to better match the body shape and habits of different users and improve the comfort of operation.

[0024] The flip switch 5 can be implemented using an integrated switch on the handle or a button or rocker switch on the combination panel; The infrared sensor 6 obstacle avoidance can be replaced by laser obstacle avoidance; the electric telescopic pole 10 can be replaced by a hydraulic lifting pole with a solenoid valve.

[0025] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
