Description

Technical Field

[0001] This invention belongs to the field of commercial vehicle cab tilting, specifically relating to an electro-hydraulic tilting mechanism and intelligent control system for a heavy-duty truck cab. Background Technology

[0002] The currently used flipping systems include the following methods:

[0003] 1. Split-type hydraulic tilting system, with independent tilting oil pump, motor and cylinder structure, connected by hydraulic oil pipes; some technical solutions adopt integrated tilting oil pump or integrated electro-hydraulic cylinder.

[0004] 2. A hydraulic locking system is used. When the cab is tilted, the system pressure increases, driving the lock to open.

[0005] 3. A handheld flip switch is used, and the switch is connected by a spiral wire.

[0006] Traditional heavy-duty truck cab hydraulic tilting mechanisms generally use a mechanical hydraulic pump combined with a decentralized hydraulic pipeline system, employing a handheld electric tilting mechanism. This has the following drawbacks: 1. Hydraulic pipelines are prone to aging and leakage, and the numerous joints result in low system reliability and high maintenance costs; 2. Operation relies on a manual tilting pump or an external electric hydraulic pump, requiring manual reversing, leading to poor tilting operability; 3. The cab tilting status depends on subjective human observation, resulting in poor monitorability; 4. There is a lack of intelligent control, making remote operation or status monitoring impossible. Summary of the Invention

[0007] The purpose of this invention is to provide an electro-hydraulic tilting mechanism and intelligent control system for heavy-duty truck cabs. Through highly integrated electro-hydraulic technology, wireless communication, and intelligent locking system, the above-mentioned problems are solved, and the user's needs for electrification and intelligence are met.

[0008] To address the aforementioned problems in the existing technology, the technical solution adopted by this invention is as follows:

[0009] An electro-hydraulic tilting mechanism and intelligent control system for a heavy-duty truck cab includes: an electro-hydraulic cylinder assembly, a cabin domain controller, an electric locking assembly, a gateway, and a remote control key;

[0010] The electro-hydraulic cylinder assembly is electrically connected to the cockpit domain controller and is used to rotate the cab.

[0011] The electric locking assembly is electrically connected to the cockpit domain controller and is used to lock the driver's cab;

[0012] The gateway is communicatively connected to the cockpit domain controller and also communicatively connected to the terminal.

[0013] The remote key is wirelessly connected to the cockpit domain controller.

[0014] Furthermore, it also includes a display screen and a buzzer alarm, both electrically connected to the cockpit domain controller. The electro-hydraulic cylinder assembly is equipped with a pressure sensor and a distance sensor, both electrically connected to the cockpit domain controller. The tilting system has a built-in tilting reminder function. The electro-hydraulic cylinder incorporates pressure and distance sensors, which monitor the hydraulic system status in real time via a network, visually displaying the tilting angle and locking status. In case of abnormalities, it triggers multi-level alarms to ensure safety.

[0015] Furthermore, the electric locking assembly includes a locking sensor and a locking motor, both of which are electrically connected to the cockpit domain controller. The electric locking device is linked to the rollover action, and the controller drives the locking motor to achieve automatic unlocking and locking. The electric locking system incorporates a locking sensor, which can monitor the locking status in real time, improving operational safety.

[0016] A heavy-duty truck cab electro-hydraulic tilting mechanism and intelligent control system mainly includes: an electro-hydraulic cylinder assembly, with the hydraulic cylinder and electric oil pump integrated into a single design, eliminating the risk of leakage in traditional hydraulic pipelines and improving system reliability; the electro-hydraulic cylinder also integrates pressure sensors and distance sensors; an electric lock, equipped with a lock sensor and lock motor, with the locking mechanism and tilting action working in a fully automatic coordinated manner, avoiding misoperation caused by manual intervention.

[0028] Example 1:

[0029] like Figure 1 , 3 As shown in Figure 4, a heavy-duty truck cab electro-hydraulic tilting mechanism and intelligent control system includes: an electro-hydraulic cylinder assembly 1, a cabin domain controller, an electric locking assembly 2, a gateway, and a remote control key;

[0030] The electro-hydraulic cylinder assembly 1 is electrically connected to the cockpit domain controller and is used to drive the cab to tilt.

[0031] The electric locking assembly 2 is electrically connected to the cockpit domain controller and is used to lock the driver's cab;

[0032] The gateway is communicatively connected to the cockpit domain controller and also communicatively connected to the terminal.

[0033] The remote key is wirelessly connected to the cockpit domain controller.

[0034] The tilting cylinder (electro-hydraulic cylinder assembly 1) integrates an electric hydraulic pump, features a fully enclosed hydraulic circuit design for the external hydraulic lines, an electric locking device for the rear suspension of the cab, and a wireless remote control and network control system.

[0035] Electro-hydraulic cylinder assembly 1: Compared to traditional tilting cylinders, the tilting cylinder integrates an electric hydraulic pump, eliminating external hydraulic lines and forming a closed hydraulic system. This reduces system hydraulic oil consumption by 7% and the number of joints by 6-14. The cylinder integrates a bidirectional oil circuit, using a motor to rotate forward and backward to extend and retract the cylinder, driving the cab tilt. Based on a standard electro-hydraulic cylinder, it incorporates a built-in pressure sensor 101 to monitor the tilting hydraulic system pressure in real time and feed it back to the controller for overload prevention; and a built-in distance sensor 102 to monitor the length of the cylinder's piston rod extension.

[0036] The wireless remote control is a key with integrated Bluetooth communication. The mobile APP communicates with the cockpit domain controller via 5G or Wi-Fi to control the cockpit rotation, realizing remote operation and status monitoring.

[0037] Wireless control system: The Bluetooth remote key integrates a flip control button and communicates with the cockpit domain controller via Bluetooth, with an effective distance of ≥30 meters; the mobile APP control is based on 5G or Wi-Fi network, supports remote command issuance for cab flipping, and real-time status monitoring; the visual feedback interface of the mobile APP displays the cab flipping angle, locking status, oil pressure data and fault codes.

[0038] Example 2:

[0039] Based on Example 1, such as Figure 2 As shown, the electro-hydraulic cylinder assembly 1 is equipped with a pressure sensor 101 and a distance sensor 102, and the pressure sensor 101 and the distance sensor 102 are electrically connected to the cockpit domain controller.

[0040] It also includes a display screen and a buzzer alarm, which are electrically connected to the cockpit domain controller. The rollover system has a built-in rollover reminder function. The electro-hydraulic cylinder has a built-in pressure sensor 101 and a distance sensor 102, which monitor the hydraulic system status in real time via the network, visually display the rollover angle and locking status, and trigger multi-level alarms in case of abnormalities to ensure safety.

[0041] The electric locking assembly 2 includes a locking sensor 201 and a locking motor 202, both of which are electrically connected to the cockpit domain controller.

[0042] The electric locking device is linked to the flipping action, and the locking motor 202 is driven by the controller to achieve automatic unlocking and locking. The electric lock has a built-in locking sensor 201, which can monitor the locking status in real time and improve operational safety.

[0043] Safety protection mechanism: The distance sensor 102 of the hydraulic cylinder is converted into the cab tilt angle and the cab position is detected in real time. If abnormal resistance is detected when the safe tilt angle is not reached, an audible and visual alarm is triggered and the operation is suspended. If the lock is not released, the system refuses to execute the tilt command.

[0044] Electric locking mechanism: An electric locking mechanism is installed at the rear overhang of the cab, which is linked to the tilting action. After the tilting command is initiated, the controller sends a signal to the locking motor 202 to open the electric lock; after the cab falls back, it automatically locks. The electric lock has a built-in locking sensor 201, which can monitor the locking status in real time.

[0045] Example 3:

[0046] Based on Example 2, a heavy-duty truck cab electro-hydraulic tilting mechanism and intelligent control system mainly includes: an electro-hydraulic cylinder assembly 1, with the hydraulic cylinder and electric oil pump integrated into one design, eliminating the risk of leakage in traditional hydraulic pipelines and improving system reliability; simultaneously, the electro-hydraulic cylinder also integrates a pressure sensor 101 and a distance sensor 102; electric locking, equipped with a locking sensor 201 and a locking motor 202, with the locking mechanism and tilting action working in full-automatic coordination, avoiding misoperation caused by manual intervention. The cockpit domain controller, remote key, and mobile APP enable near-field one-button operation via Bluetooth key, while the mobile APP supports remote control and data visualization, monitoring the locking status, oil pressure, and angle in real time through a sensor network, triggering multi-level alarms in case of abnormalities.

[0047] Specific working principle: The electric locking device is opened by remote key or mobile APP. If the electric locking device cannot be opened, an alarm command is triggered and alarm information is displayed. If the electric locking device is opened normally, the cylinder rod of the electro-hydraulic cylinder assembly 1 is extended, and the tilting angle and pressure information are displayed at the same time. When the cab has not completed tilting, it is displayed that it is tilting. When the cab has completed tilting, the tilting stops.

[0048] 1. Working process of electric hydraulic cylinder:

[0049] Cab tilting: The user sends a command via remote control or mobile APP → the tilting relay drives the oil pump motor to rotate forward → the internal oil pressure of the hydraulic system increases → the piston rod of the electric hydraulic cylinder extends, pushing the cab to tilt;

[0050] Cab retraction: The user sends a command via remote control or mobile APP → the flip relay drives the oil pump motor to reverse → the oil pump supplies oil to the upper chamber of the oil cylinder → the oil cylinder piston retracts, pushing the cab to retract.

[0051] In this embodiment, the electro-hydraulic cylinder integrates a pressure sensor 101 to detect the internal pressure of the system in real time. When the pressure is abnormal, an alarm is triggered and the tilting stops. The integrated distance sensor 102 detects the cylinder extension, which is converted by the cockpit domain controller to output the cab tilting angle and displayed visually on the intelligent port.

[0052] 2. Locking mechanism control logic: Tilting command triggered → Locking motor 202 rotates → Locking opens → Controller detects locking sensor 201 signal → If locking is released, cab tilting is executed; if not released, tilting command is rejected.

[0053] In this embodiment, after receiving the flip command, the cockpit domain controller instructs the drive locking motor 202 to rotate and open the electric lock. After the electric lock is opened, the locking sensor 201 sends a signal to the cockpit domain controller to perform the flip operation. Conversely, if the lock opening is abnormal, the locking sensor 201 sends a signal to the cockpit domain controller to refuse to execute the flip command and displays an alarm message.

[0054] 3. Example of mobile APP function: After logging in, the user selects the vehicle → views the real-time flip angle (dynamic display of 3D model) → clicks the "Flip" button → the system detects the locking status → executes the flip action and displays the progress.

[0055] This invention is not limited to the above-described optional embodiments. Anyone can derive other various forms of products under the guidance of this invention. However, regardless of any changes made in their shape or structure, any technical solution that falls within the scope of the claims of this invention shall be protected by this invention.
