[0002] In the current market application of mechanical structures, reliability is becoming increasingly important. For the driver's cab tilting locking structure, there are various control methods, but none of these methods have backup solutions. They are used to address the problem of inability to perform functions due to the failure of the main control method, and their reliability is generally low. This utility model aims to solve this problem. Utility Model Content
[0003] The purpose of this utility model is to provide a driver's cab tilting locking mechanism and vehicle. By providing a handle on the auxiliary hook, when the push rod fails to extend and drive the auxiliary hook to rotate, the auxiliary hook can be driven to rotate by the handle, thereby improving reliability.
[0004] To solve the above technical problems, the following technical solution is adopted:
[0005] In the first aspect, this utility model provides a driver's cab tilting locking mechanism, including a main hook, an auxiliary hook and a push rod installed on the guard plate; the auxiliary hook is equipped with a handle for driving the auxiliary hook to rotate, the push rod is used to drive the auxiliary hook to rotate, and one end of the main hook is provided with a groove for installing the driver's cab locking seat pin.
[0006] The main hook and the auxiliary hook are equipped with return springs, which enable the main hook and the auxiliary hook to rotate in one direction without external force. The guard plate is also equipped with a sensor for detecting the state of the main hook or the auxiliary hook.
[0007] When the driver's cab is not tilted, the lock seat pin is located in the groove on the main hook, the main hook is closed, and the lock seat pin is locked by the limit of the main hook by the auxiliary hook and its return spring.
[0008] When the driver's cab is tilted, the push rod or the handle drives the auxiliary hook to rotate, releasing the restriction on the main hook. The main hook is then opened by rotating the return spring on it, and the lock seat pin is unlocked.
[0009] Optionally, the main hook, auxiliary hook, and push rod are all installed between two guard plates, which are mounted on the driver's cab, and the handle extends from the guard plate.
[0010] Optionally, the return spring includes a main hook return spring disposed on the main hook and an auxiliary hook return spring disposed on the auxiliary hook. The main hook is mounted on the guard plate via a main hook pin, and the main hook return spring is disposed on the main hook pin. The main hook return spring has a tendency to open the main hook.
[0011] The auxiliary hook is mounted on the guard plate via an auxiliary hook pin, and the auxiliary hook return spring is disposed on the auxiliary hook pin. The auxiliary hook return spring has the tendency to drive the auxiliary hook to rotate and thus drive the main hook to close.
[0012] Optionally, the sensor includes a sensor one for detecting the position of the auxiliary hook and a sensor two for detecting the position of the main hook. Both sensors are equipped with sensor electrical harnesses, and both sensors are connected to the display system in the driver's cab through the sensor electrical harnesses. When the auxiliary hook rotates to contact sensor one or the main hook rotates to contact sensor two, a signal is sent to the display system to unlock or lock the lock seat pin.
[0013] Optionally, both sensor one and sensor two are provided with baffles, and sensor one and sensor two contact the auxiliary hook and the main hook through the baffles.
[0014] Optionally, the push rod includes either an electric push rod or a hydraulic push rod.
[0015] Optionally, the push rod is mounted on a mounting bracket, which is disposed on the protective plate.
[0016] Secondly, this utility model provides a vehicle including the driver's cab tilting locking mechanism described in any one of the first aspects.
[0017] Compared with the prior art, the beneficial effects achieved by this utility model are as follows:
[0018] The locking mechanism provided by this utility model has a handle on the auxiliary hook. When the push rod cannot be pushed out, the handle is used to control the rotation of the auxiliary hook, thereby controlling the rotation of the main hook, realizing the locking and unlocking of the lock seat pin, improving the reliability of the device. By setting a sensor to detect the position of the main hook or the auxiliary hook, the lock seat pin is determined to be in a locked or unlocked state, and subsequent operations are determined based on the state of the lock seat pin, thereby improving the safety of the device.

[0033] Example 1
[0034] like Figure 1 As shown, this embodiment provides a driver's cab tilting locking mechanism, including a main hook 1, an auxiliary hook 2 and a push rod 5 installed on the guard plate 3; the auxiliary hook 2 is equipped with a handle 6 for driving the auxiliary hook 2 to rotate, the push rod 5 is used to drive the auxiliary hook 2 to rotate, and one end of the main hook 1 is provided with a groove for installing the driver's cab locking seat pin 4.
[0035] The main hook 1 and the auxiliary hook 2 are provided with return springs, which enable the main hook 1 and the auxiliary hook 2 to rotate in one direction without external force. The guard plate 3 is also provided with a sensor for detecting the state of the main hook 1 or the auxiliary hook 2.
[0036] The guard plate 3 has two sensors, which are located on the sides of the main hook 1 and the auxiliary hook 2 respectively. When the main hook 1 and the auxiliary hook 2 rotate, they come into contact with the sensors to determine the position of the main hook 1 and the auxiliary hook 2, thereby determining whether the locking seat pin 4 is locked. When the two sensors come into contact, they send a signal to the vehicle's display system to display the status of the locking seat pin 4.
[0037] The return spring on the main hook 1 has a tendency to drive the main hook 1 to rotate counterclockwise, and the return spring on the auxiliary hook 2 has a tendency to drive the auxiliary hook 2 to rotate clockwise. When the main hook 1 rotates counterclockwise, it is in the open state, and when the auxiliary hook 2 rotates clockwise, it restricts the main hook 1 from opening.
[0038] like Figure 7 , Figure 8 As shown, the lock seat pin 4 is installed on the driver's cab. When the driver's cab is tilted, it follows the movement of the driver's cab. The tilting of the driver's cab is achieved by the tilting mechanism.
[0039] like Figure 1 As shown, when the driver's cab is not tilted, the lock seat pin 4 of the driver's cab needs to be locked to prevent tilting and affect use. The lock seat pin 4 is located in the groove of the main hook 1 to achieve locking. At this time, the main hook 1 is closed, and the auxiliary hook 2 limits the main hook 1 under the action of the return spring, restricting the main hook 1 from opening under the action of the return spring.
[0040] like Figure 2 , Figure 3 As shown, when the driver's cab needs to be tilted, the push rod 5 is first extended to act on the auxiliary hook 2, or the handle 6 drives the auxiliary hook 2 to rotate counterclockwise. When the counterclockwise rotating auxiliary hook 2 contacts the side sensor, it indicates that the auxiliary hook 2 has been opened. The sensor sends a signal indicating that the tilting mechanism can be operated. At this time, since the lock seat pin 4 has not yet been driven by the tilting mechanism, it is still located in the groove of the main hook 1 and plays a limiting role on the main hook 1. The main hook 1 cannot rotate counterclockwise under the action of the return spring. When the tilting mechanism is started, after the lock seat pin 4 moves, the lock seat pin 4 rotates counterclockwise under the action of the return spring, and the lock seat pin 4 is unlocked.
[0041] Example 2
[0042] like Figure 1 , Figure 5 , Figure 6 As shown, this embodiment provides a driver's cab tilting locking mechanism based on embodiment one. The guard plate 3 is provided in two pieces. The main hook 1, auxiliary hook 2 and push rod 5 are located between the two guard plates 3. The two guard plates 3 are connected by a pin. The guard plate 3 is installed on the upper frame of the driver's cab and is located below the lock seat pin 4. The lock seat pin 4 is located above the guard plate 3. The upper end of the guard plate 3 is provided with a notch. The lock seat pin 4 is located in the notch and is locked in the groove of the main hook 1.
[0043] like Figure 9 , Figure 10 As shown, the lower end of the guard plate 3 is provided with a U-shaped groove, through which the guard plate 3 is installed on the driver's cab frame.
[0044] A mounting bracket is also provided on the guard plate 3, and the push rod 5 is mounted on the mounting bracket. The push rod 5 can be an electric push rod 5 or a hydraulic push rod 5. The telescopic end of the push rod 5 acts on the auxiliary hook 2. When the telescopic end of the push rod 5 extends, it drives the auxiliary hook 2 to rotate counterclockwise. When the telescopic end retracts, the return spring on the auxiliary hook 2 drives the auxiliary hook 2 to rotate clockwise.
[0045] The main hook 1 is mounted on the guard plate 3 via a main hook pin 7. A main hook return spring 8 is mounted on the main hook pin 7, which tends to drive the main hook 1 to rotate counterclockwise, thus opening the main hook 1. The auxiliary hook 2 is mounted on the guard plate 3 via an auxiliary hook pin 9, which is equipped with an auxiliary hook return spring 10. The auxiliary hook return spring 10 tends to drive the auxiliary hook 2 to rotate clockwise. The main hook 1 and auxiliary hook 2 are in contact. Under the action of the auxiliary hook return spring 10, the auxiliary hook 2 restricts the main hook 1 from opening. When the auxiliary hook 2 does not restrict the main hook 1, the main hook 1 can automatically open under the action of the main hook return spring 8. However, when the lock seat pin 4 is not driven, the lock seat pin 4 is located in the groove of the main hook 1, and the lock seat pin 4 can still restrict the main hook 1 from opening automatically. Only when the lock seat pin 4 is driven to rotate, the main hook 1 rotates counterclockwise under the action of the main hook return spring 8. After rotating to the position, one side of the main hook 1 contacts the auxiliary hook 2 and cannot continue to rotate, indicating that the main hook 1 is fully open and the lock seat pin 4 is unlocked.
[0046] The two sensors are sensor 11 and sensor 12. Sensor 11 is installed on one edge of the guard plate 3, located on the side of the auxiliary hook 2. Sensor 12 is installed on the other side of the guard plate 3, located on the side of the main hook 1. The two sensors are connected to sensor electrical harness 14, which is connected to the vehicle's display system. The status of the main hook 1 and auxiliary hook 2 is determined by the sensors. This ensures that the locking seat pin 4 can be driven when the tilting device is opened, preventing malfunctions in the locking mechanism. The tilting device is opened when the locking seat pin 4 is locked, ensuring the safety of the mechanism.
[0047] Both sensor 11 and sensor 2 12 are provided with baffles 13, which contact the auxiliary hook 2 and the main hook 1 through the baffles 13. When the baffles 13 contact the sensors, they increase the contact area when the auxiliary hook 2 and the main hook 1 trigger the sensors, ensuring that they can contact the sensors after being rotated into position.
[0048] After the auxiliary hook 2 is driven by the push rod 5 or the handle 6 to rotate counterclockwise into position, the side of the auxiliary hook 2 contacts the baffle 13, and the baffle 13 contacts the sensor 11. The sensor 11 sends a signal to the display system, indicating that the auxiliary hook 2 is open, indicating that the flipping mechanism can be started. The sensor 2 can be adjusted in position so that it contacts the sensor 2 when the main hook 1 is open or when the main hook 1 is closed.
[0049] like Figure 2 , Figure 3As shown, when sensor 12 is installed in the upper position, one end of the main hook 1 contacts the baffle 13 when it is open, and the baffle 13 contacts sensor 12. Sensor 12 sends a signal to the display system, indicating that the main hook 1 is open. When sensor 12 does not send a signal, it indicates that the push rod 5 can be controlled to retract, so that the auxiliary hook 2 rotates clockwise to limit the main hook 1.
[0050] like Figure 4 As shown, when sensor 12 is installed in the lower position, one end of the main hook 1 contacts the baffle 13 when the main hook 1 is closed. The baffle 13 contacts sensor 12, and sensor 12 sends a signal to the real system to indicate that the main hook 1 is closed. This can control the push rod 5 to retract, so that the auxiliary hook 2 rotates clockwise to limit the main hook 1.
[0051] In use, the push rod 5 is selected as either an electric push rod or a hydraulic push rod, controlled by an electrical signal or hydraulic oil, and has two states: extended and retracted. The auxiliary hook 2 is mounted on the auxiliary hook pin 9 and is equipped with a return spring. Without external force, it tends to rotate clockwise, which is limited by the push rod 5. The main hook 1 is mounted on the main hook pin 7 and is equipped with a return spring. Without external force, it tends to rotate counterclockwise, which is limited by the auxiliary hook 2. When the auxiliary hook 2 rotates counterclockwise to the position sensor of the baffle 13, it contacts the sensor, and the system receives a signal.
[0052] like Figure 1 As shown, the electric actuator 5 is in the retracted state, the auxiliary hook 2 is pressed against the actuator 5 under the return spring, and the main hook 1 is pressed against the auxiliary hook 2 under the limit of the auxiliary hook 2, and is in the closed state.
[0053] When push rod 5 extends, as Figure 2 As shown. The auxiliary hook 2 rotates counterclockwise under the action of the push rod 5. When the push rod 5 extends to its position, the auxiliary hook 2 rotates to a certain angle and touches the sensor 11, indicating that it is trying to open the mechanical lock. The main hook 1 has a tendency to rotate counterclockwise, and the limit of the auxiliary hook 2 on the main hook 1 disappears, but the lock seat pin 4 still has a limit on the main hook 1.
[0054] When a signal is received from sensor 11, the flipping mechanism can be activated, driving the locking pin of the lock seat to move upwards. During this movement, the main hook 1 rotates counterclockwise synchronously until it is fully open. Figure 3 As shown.
[0055] When the driver's cab tilting mechanism needs to be closed, the control mechanism starts to activate, and the driver's cab lock seat pin 4 gradually approaches the main hook 1 (e.g., Figure 3 In the current state, under the force of the lock seat pin 4, the main hook 1 rotates clockwise and simultaneously locks the lock seat pin 4, achieving a locking effect. When it is visually observed that the driver's cab is closed, the push rod 5 sends a signal, the push rod 5 retracts, and the auxiliary hook 2 rotates clockwise back to its original position under the return spring, limiting the main hook 1 and achieving a locking effect.
[0056] When the position of sensor 212 is adjusted, such as Figure 4 Status. Sensor 12 can be used to detect whether the main hook 1 has returned to its original position (equivalent to detecting whether the driver's cab is closed). When the main hook 1 returns to its original position, it contacts sensor 12, indicating that it has returned to its original position. This can replace the step of visually checking whether the driver's cab is closed.
[0057] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
