AI Technical Summary
The hydraulic cylinder controller of the existing truck cab bolt controller is prone to fatigue damage, the seals are prone to leakage, resulting in environmental pollution, and it fails at low temperatures, resulting in a high failure rate.
An electric controller is used, which utilizes a combination of a geared motor, rollers, wire rope and torsion spring. The motor drives the rollers to rotate, which in turn drives the unlocking and locking hooks to open and close the bolt, thus avoiding the use of a hydraulic system.
It can operate normally in low-temperature environments below -35 degrees Celsius, reducing the failure rate, reducing environmental pollution, and increasing service life. It also has a compact structure and is energy-saving.

Abstract
Description
Technical Field
[0001] This utility model relates to an electric control device, and in particular to an electric control device capable of controlling the locking bolts of a truck cab. Background Technology
[0002] Currently, the commonly known truck cab locking bolt controller is a hydraulic cylinder controller. This controller uses a hydraulic valve to control the high-pressure hydraulic oil in the cylinder, which pushes the piston rod to unlock. When there is no high-pressure hydraulic oil in the cylinder, the torque of the locking bolt torsion spring controls the unlocking and locking hooks. However, the seals of this type of hydraulic cylinder controller are prone to fatigue damage, malfunction at temperatures as low as -35 degrees Celsius, leak oil, pollute the environment, and have a high failure rate. Summary of the Invention
[0003] To reduce the failure rate of hydraulic cylinder controllers, minimize environmental pollution, prevent seal fatigue damage, and ensure normal operation at temperatures below -35 degrees Celsius, this invention provides a controller. This controller is compact, simple in structure, causes no environmental pollution, operates normally at temperatures below -35 degrees Celsius, and has a long service life.
[0004] The technical solution adopted by this utility model to solve the technical problem is as follows: the first shaft (2) is connected to the cab (1), the locking hook (3) is hinged to the third shaft (5), the third shaft (5) is connected to the bolt body (7), the first torsion spring (6) is sleeved to the third shaft (5), the second shaft (4) is connected to the bolt body (7), the fourth shaft (8) is connected to the bolt body (7), the second torsion spring (13) is sleeved to the fourth shaft (8), the fifth shaft (9) is connected to the bolt body (7), the sixth shaft (10) is connected to the bolt body (7), the unlocking hook (11) is hinged to the fourth shaft (8), the two ends of the wire rope (12) are respectively connected to the unlocking hook (11) and the roller (14), the roller (14) is connected to the output shaft of the reduction motor (15), and the reduction motor (15) is connected to the bolt body (7). See Figure 1 The unlocking mechanism works as follows: when the geared motor (15) rotates forward, it drives the roller (14) to rotate clockwise. The roller (14) pulls the unlocking hook (11) through the wire rope (12), overcoming the torque of the second torsion spring (13) and the first torsion spring (6), and rotates counterclockwise around the fourth shaft (8). The unlocking hook (11) rotates counterclockwise and contacts the sixth shaft (10). See Figure 2 The cab (1) drives the first shaft (2) to move upward. The torque of the first torsion spring (6) drives the locking hook (3) to rotate counterclockwise around the third shaft (5) and contact the second shaft (4). See Figure 3 The locking mechanism works by the cab (1) driving the first shaft (2) downwards. The weight of the cab (1) drives the first shaft (2) to press down the locking hook (3), overcoming the torque of the first torsion spring (6). The locking hook (3) rotates clockwise around the third shaft (5) until... Figure 2 When the geared motor (15) reverses, the torque of the second torsion spring (13) drives the unlocking hook (11) to rotate clockwise around the fourth shaft (8) until the unlocking hook (11) contacts the fifth shaft (9). The unlocking hook (11) then drives the roller (14) to rotate counterclockwise via the wire rope (12). Figure 1 Location.
[0005] The advantages of this utility model are that it is fully functional, compact in structure, pollution-free, energy-saving, and has a long service life. In particular, it works normally at temperatures below -35 degrees Celsius and can be used in various tiltable cabs of automobiles. Attached Figure Description

Detailed Implementation
[0011] Figure 1 This is a schematic diagram of the locking state control principle of the cab 1 bolt. The first shaft 2 is connected to the cab 1. The locking hook 3 is hinged to the third shaft 5. The third shaft 5 is connected to the bolt body 7. The first torsion spring 6 is sleeved on the third shaft 5. The second shaft 4 is connected to the bolt body 7. The fourth shaft 8 is connected to the bolt body 7. The second torsion spring 13 is sleeved on the fourth shaft 8. The fifth shaft 9 is connected to the bolt body 7. The sixth shaft 10 is connected to the bolt body 7. The unlocking hook 11 is hinged to the fourth shaft 8. The two ends of the wire rope 12 are connected to the unlocking hook 11 and the roller 14 respectively. The roller 14 is connected to the output shaft of the reduction motor 15. The reduction motor 15 is connected to the bolt body 7.
[0012] Figure 2 This is a control principle diagram for the unlocking hook 11 to the unlocked state when the cab 1 is not moved. When the reduction motor 15 rotates forward, it drives the roller 14 to rotate clockwise. The roller 14 pulls the unlocking hook 11 through the steel wire rope 12 to overcome the torque of the second torsion spring 13 and the first torsion spring 6 and rotates counterclockwise with the fourth shaft 8 as the center. The unlocking hook 11 rotates counterclockwise and contacts the sixth shaft 10.
[0013] Figure 3 This is a schematic diagram of the control principle for the locking and unlocking state of the cab 1. The cab 1 drives the first shaft 2 to move upward. The torque of the first torsion spring 6 drives the locking hook 3 to rotate counterclockwise around the third shaft 5 and contact the second shaft 4.
[0014] The electric controller for the truck cab bolt provided by this utility model has a geared motor 15 that rotates forward and reverse. The first torsion spring 6 and the second torsion spring 13 control the roller 14 and the wire rope 12 to make the unlocking hook 11 and the locking hook 3 rotate counterclockwise and clockwise with the fourth axis 8 and the third axis 5 as the center, respectively, so as to realize the unlocking and locking of the cab bolt 1.
[0015] This utility model transmits the unlocking force through the reduction motor 15, roller 14, wire rope 12, unlocking hook 11, and first torsion spring 6, and transmits the locking force through the torque of the locking hook 3 and second torsion spring 13 under the weight of the cab 1, thereby realizing the unlocking and locking control functions of the truck cab.
