DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] In order to further explain the technical solution of the utility model, the following is elaborated in detail through specific embodiments.

[0021] Please refer to Figure 1 , the utility model provides an excitation controller for a generator set, including a controller main body 1, a mounting bracket 2, an installation cavity 3 and a quick disassembly and assembly mechanism 4. The front side of the mounting bracket 2 is provided with an installation cavity 3, the controller main body 1 is inserted into the inner side of the installation cavity 3, and quick disassembly and assembly mechanisms 4 are arranged on both sides of the controller main body 1 and both sides of the installation cavity 3.

[0022] Please refer to Figures 2-5, the present utility model provides an excitation controller for a generator set. The quick disassembly and assembly mechanism 4 includes a guide groove 41, a lock hole 42, a guide rail 43, a sliding cavity 44, a locking tongue 45, a double-shaft motor 46, a screw 47, and a control panel 48. Guide grooves 41 are symmetrically arranged on both sides of the installation cavity 3, and lock holes 42 are symmetrically arranged on the upper and lower sides of the guide groove 41. Guide rails 43 are symmetrically installed with screws on the left and right sides of the controller body 1. The guide rails 43 can be slidably docked with the inner side of the guide groove 41. Sliding cavities 44 are symmetrically arranged on the upper and lower sides of the guide rail 43, and a locking tongue 45 is slidably installed inside the sliding cavity 44. The locking tongue 45 can be engaged with the inner side of the lock hole 42. A double-shaft motor 46 is installed inside the guide rail 43. The double-shaft motor 46 is located between the two sliding cavities 44. Screw 47 is installed on the output shafts of the upper and lower parts of the double-shaft motor 46. The screw 47 extends into the inner side of the sliding cavity 44 and is threadedly connected to the threaded hole on the surface of the locking tongue 45. The control panel 48 is installed on the front panel of the controller body 1. The double-shaft motor 46 is connected to the control panel 48 for control. By starting the double-shaft motor 46 through the control panel 48, the double-shaft motor 46 drives the screw 47 to rotate, so that the screw 47 pushes the locking tongue 45 outwards from the sliding cavity 44 until the locking tongue 45 is engaged with the lock hole 42, thereby locking the position of the guide rail 43 and the guide groove 41, and making the controller body 1 and the installation cavity 3 firmly engaged with each other, thus realizing the installation and fixation of the controller body 1 and the mounting bracket 2.

[0023] Further explanation, a fingerprint recognition module 48a is arranged at the front part of the control panel 48, so that the quick disassembly and assembly mechanism 4 has a biometric recognition function, and the unlocking method has exclusivity, avoiding others from operating the quick disassembly and assembly mechanism 4 to disassemble and remove the controller body 1 by themselves.

[0024] Further explanation, a power supply compartment 49 is opened on the outer side of the guide rail 43. The power supply compartment 49 is electrically connected to the control panel 48, and the power supply compartment 49 is powered by a battery. The quick disassembly and assembly mechanism 4 is independently powered by the power supply compartment 49, which is convenient to use.

[0025] Further explanation, the telescopic stroke distance of the locking tongue 45 is not less than 2.5 cm, and the depth of the lock hole 42 is not less than 2.5 cm, ensuring that there is enough connection length between the locking tongue 45 and the lock hole 42 to ensure the stability of the engagement.

[0026] Further explanation, a gasket 410 is laid on the rear side wall of the controller body 1. The thickness of the gasket 410 is not less than 1 cm. The gasket 410 can fill the gap between the controller body 1 and the installation cavity 3, so that the controller body 1 can be kept stable and not easy to shake after installation.

[0027] Further explanation, when the controller body 1 is completely inserted into the inner side of the installation cavity 3, the locking tongue 45 and the lock hole 42 are in the same vertical direction.

[0028] The working principle is as follows:

[0029] First, replace the battery of the power supply compartment 49 with a new one to ensure that the quick disassembly and assembly mechanism 4 has sufficient power for continuous operation.

[0030] Second, when installing the controller body 1, first align the guide rail 43 with the guide groove 41, and then push the controller body 1 into the inner side of the installation cavity 3. When the controller body 1 is completely installed inside the installation cavity 3, the positions of the locking tongue 45 and the locking hole 42 correspond. At this time, the user needs to first unlock it through the fingerprint recognition module 48a to obtain the operation permission of the control panel 48. After that, the biaxial motor 46 can be started through the control panel 48. The biaxial motor 46 drives the screw 47 to rotate, so that the screw 47 pushes the locking tongue 45 outwards from the sliding cavity 44 until the locking tongue 45 is engaged in the locking hole 42, thereby locking the position of the guide rail 43 and the guide groove 41, and making the controller body 1 and the installation cavity 3 firmly clamped to each other, thus realizing the installation and fixation of the controller body 1 and the mounting bracket 2. The operation is simple and convenient, and no additional tools are required during the process, which greatly improves the disassembly and assembly efficiency of the controller body 1. And because the unlocking method of the fingerprint recognition module 48a has exclusivity, it prevents others from operating the quick disassembly and assembly mechanism 4 to remove the controller body 1 by themselves, ensuring the safety of the controller body 1 on the basis of being easy to disassemble and assemble.

[0031] Third, when disassembling the controller body 1, the user also needs to first unlock it through the fingerprint recognition module 48a to obtain the operation permission of the control panel 48. Then start the biaxial motor 46 through the control panel 48, and let the screw 47 drive the locking tongue 45 to disengage from the locking hole 42 and retract into the sliding cavity 44, then the connection and fixation between the controller body 1 and the mounting bracket 2 can be released. Finally, take out the controller body 1 from the inner side of the installation cavity 3 to complete the disassembly, and the operation is convenient.

[0032] The above are only the preferred examples of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
