[0028] Referring to Figure 1 A cab tiltable forklift truck, a cab 20 is rotatably mounted on a vehicle body 10 of the forklift truck, specifically, the cab 20 can be flipped towards the width direction of the forklift truck, so as to facilitate maintenance personnel to overhaul components located below the cab 20;

[0029] Further, the forklift truck further comprises:

[0030] The electric push rod 11 is installed on the part of the forklift below the cab 20, and the electric push rod 11 comprises a motor 113 and a power supply 114. The motor 113 is rotated to make the telescopic rod 111 perform telescopic movement. Specifically, when the positive electrode of the motor 113 is powered, the telescopic rod 111 extends outward, and when the negative electrode of the motor 113 is powered, the telescopic rod 111 retracts inward. The base end of the electric push rod 11 is rotatably installed in the forklift, and the telescopic end of the telescopic rod 111 is rotatably installed at the bottom of the cab 20.

[0031] When it is needed to turn up the cab 20, the positive electrode of the motor 113 of the electric push rod 11 is powered, and the telescopic rod 111 is ejected to laterally overturn the cab 20, as shown in FIG. 2. Figures 1-2 When it is needed to return the cab 20 to the original position, the negative electrode of the motor 113 is powered, and the motor 113 is reversed to make the telescopic rod 111 retract inward to pull back the overturned cab 20 to the original position, as shown in FIG. 3. Figures 2-1

[0032] The forklift further comprises a locking mechanism 30 for fixing the cab 20. Specifically, the locking mechanism 30 comprises:

[0033] The buckle 31 is installed on the side of the cab 20.

[0034] The base 32 is installed on the vehicle body 10, and the position of the base 32 corresponds to the position of the buckle 31. Further, the buckle 31 has a bent section 311, and a locking hole 313 is formed at the end of the bent section 311. The included angle between the bent section 311 and the rest of the buckle 31 is 90°, so that the entire buckle 31 is in the shape of L. A threaded locking groove 321 is formed in the part of the base 32 corresponding to the locking hole 313. The locking mechanism 30 further comprises a locking bolt 33, which can be embedded into the threaded locking groove 321 through the locking hole 313. After being embedded, the locking bolt 33 can lock the cab 20 to the normal use posture, as shown in FIG. 4. Figure 1

[0035] Based on the further improvement of the above structure, the locking mechanism 30 further comprises a shock-absorbing pad 34 installed on the base 32, and the part of the buckle 31 connected to the vehicle body 10 is provided with a through hole 312.

[0036] The middle part of the shock-absorbing pad 34 has a recessed part 341. When the cab 20 is turned back to the normal state, the top of the shock-absorbing pad 34 passes through the through hole 312, so that the part of the buckle 31 in the through hole 312 is buckled in the recessed part 341. At this time, the bottom of the buckle 31 abuts against the rest of the shock-absorbing pad 34 to achieve the shock-absorbing effect, avoiding the cab 20 from being damaged after returning to the original position.

[0037] The forklift further comprises a control unit for controlling the telescopic movement of the telescopic end of the electric push rod 11 and the telescopic stroke of the telescopic end of the electric push rod 11. Specifically:​​

[0038] The control unit comprises:

[0039] A controller 12 is installed on the forklift truck, the controller 12 controls the extension or retraction of the telescopic end of the electric push rod 11 through a control circuit, the controller 12 is provided with a forward rotation control button 121 and a reverse rotation control button 122, as shown in Figure 3 ;

[0040] A magnet 1111 is installed on the telescopic rod 111 of the electric push rod 11, the position of the magnet 1111 changes with the extension and retraction of the telescopic rod 111;

[0041] A first inductor 1121 and a second inductor 1122 are respectively installed on the shell 112 of the electric push rod 11, the inductors are used to sense the position of the magnet 1111, when the inductors sense that the magnet 1111 is at a position corresponding to the inductors, the control stops the extension and retraction of the electric push rod 11, in particular:

[0042] The control unit further comprises a button power supply 13, a first relay 14 and a second relay 15;

[0043] The electric push rod 11 further comprises a motor 113 and a power supply 114, the forward rotation of the motor 113;

[0044] The positive and negative poles of the power supply 114 are connected to the positive and negative poles of the motor 113 through the load end of the first relay 14 and the load end of the second relay 15, and can be switched to each other;

[0045] The control circuit comprises:

[0046] The forward rotation control circuit comprises the button power supply 13, the first inductor 1121, the forward rotation control button 121 and the control circuit of the first relay 14 connected in series with each other;

[0047] The reverse rotation control circuit comprises the button power supply 13, the second inductor 1122, the reverse rotation control button 122 and the control circuit of the second relay 15 connected in series with each other;

[0048] As Figure 9As shown, the first relay 14 and the second relay 15 are both five-pin relays, having 85, 86 (control circuit), 87 (normally open contact), 87a (normally closed contact), 30 (common terminal). When the forward rotation control button 121 is pressed (the forward rotation control button 121 is a normally closed control button, which needs to be pressed for a long time to make the circuit closed), the control circuit of the first relay 14 is energized, the coil of the first relay 14 is energized, and the contact state changes, so that the 30 changes from being connected to 87a to being connected to 87. At this time, the power supply 114 can supply power to the positive electrode of the motor 113 through the first relay 14, and the telescopic rod 111 of the electric push rod 11 starts to extend.

[0049] As the telescopic rod 111 extends, the magnet 1111 reaches the position corresponding to the first inductor 1121. When the first inductor 1121 senses the magnet 1111, the forward rotation control circuit is disconnected. At this time, the coil of the first relay 14 loses power, the contact state changes, so that the 30 changes from being connected to 87 to being connected to 87a, and the power supply 114 cannot continue to supply power to the motor 113. The telescopic rod 111 of the electric push rod 11 stops.

[0050] At this time, the position of the magnet 1111 is on the position of the first inductor 1121, and the forward rotation control circuit is always in an open state. At this time, the motor 113 can only be controlled to reverse through the reverse rotation control circuit.

[0051] Specifically, when the reverse rotation control button 122 is pressed (the reverse rotation control button 122 is a normally closed control button, which needs to be pressed for a long time to make the circuit closed), the control circuit of the second relay 15 is energized, the coil of the second relay 15 is energized, and the contact state changes, so that the 30 changes from being connected to 87a to being connected to 87. At this time, the power supply 114 can supply power to the negative electrode of the motor 113 through the second relay 15, and the telescopic rod 111 of the electric push rod 11 starts to retract.

[0052] As the telescopic rod 111 extends, the magnet 1111 reaches the position corresponding to the first inductor 1121. When the first inductor 1121 senses the magnet 1111, the forward rotation control circuit is disconnected. At this time, the coil of the first relay 14 loses power, the contact state changes, so that the 30 changes from being connected to 87 to being connected to 87a, and the power supply 114 cannot continue to supply power to the motor 113. The telescopic rod 111 of the electric push rod 11 stops.

[0053] Through the above operation, the extension and retraction amount of the telescopic rod 111 can be controlled, and the overturning angle of the cab 20 is avoided to be too large.

[0054] In the description of the utility model, need explain, the term "center" "upper" "lower" "left" "right" "vertical" "horizontal" "inner" "outer" and so on indicate the direction or position relation is based on the direction or position relation shown in the drawing, only for the convenience of describing the utility model and simplifying the description, and is not indicate or imply the device or element indicated must have a particular direction, with a particular direction structure and operation, therefore can not be understood as the limitation to the utility model.

[0055] Those skilled in the art should understand that the above embodiments are only for clearly illustrating the utility model, and not limiting the scope of the utility model. Based on the above disclosure, other changes or modifications can also be made by those skilled in the art, and these changes or modifications are still within the scope of the utility model.
