That is, the entire disassembly and assembly mechanism 40 for the detection module is installed on the assembly bracket 31, with high repeat assembly consistency and accurate displacement detection of the power module 20. The detection unit 42 is detachably installed on the buckle bracket 41, and the position of the detection unit 42 on the buckle bracket 41 can be adjusted, making disassembly and assembly convenient.

When the buckle bracket 41 is assembled to the assembly bracket 31, the detection unit 42 and the power supply board 33 are connected in plugging and conduction so that the power supply board 33 supplies power to the detection unit 42.

For example, the power supply board 33 is provided with a plugging female head 34, and the circuit board 421 is provided with a plugging male head 423. When the buckle bracket 41 is buckled and assembled to the assembly bracket 31, the pins of the plugging male head 423 are inserted into the plugging female head 34 and conduct electricity.

[0032] In a preferred embodiment, the buckle holder 41 includes a tray portion 411 and buckle pins 412 distributed on both sides of the tray portion 411. The buckle pins 412 are inserted into the buckle connection control module 30, and the detection unit 42 is detachably mounted on the tray portion 411. Optionally, the detection unit 42 includes a circuit board 421 and at least one detection element 422 mounted on the circuit board 421. The detection element 422 is used to sense the moving position of the power module 20. The circuit board 421 is in a plate-like structure, and the detection element 422 protrudes from the circuit board 421 to form a detection structure.

[0033] As Figures 3 to 5 shown, the tray portion 411 is used to position and mount the detection unit 42 to define the installation position and installation stroke of the circuit board 421. For example, the tray portion 411 performs planar positioning on the circuit board 421 to form a planar positioning installation. For example, the tray portion 411 and the circuit board 421 are in planar contact. Or, the tray portion 411 performs edge positioning on the circuit board 421 to form a lateral positioning installation. For example, the tray portion 411 is provided with a chute or a notch groove to define the edge of the circuit board 421.

[0034] The buckle pins 412 are distributed on both sides of the tray portion 411 to form a double-sided insertion and fixation. Optionally, the detection unit 42 is located between the two sets of buckle pins 412, so that the detection unit 42 and the buckle pins 412 are on the same side of the tray portion 411. Optionally, the detection unit 42 and the two sets of buckle pins 412 are arranged back to back on the tray portion 411, so that the detection unit 42 and the buckle pins 412 are on the opposite sides of the tray portion 411. Further preferably, the detection unit 42 is locked to the back of the tray portion 411 through a fastener 43 to form a locking connection.

Preferably, a chamfered surface is provided at the end of the inverted buckle to guide the elastic buckle 4121 to bend and deform during insertion, improving the smoothness of insertion.

[0036] In a preferred embodiment, the buckle pins 412 on each side further include balance columns 4122 spaced apart from the elastic buckles 4121. An elastic space is formed between the balance columns 4122 and the elastic buckles 4121. The balance columns 4122 and the elastic buckles 4121 are inserted into the assembly holes 32 of the control module 30. The balance columns 4122 and the elastic buckles 4121 are spaced apart.

The support plate portion 411 assembles and supports the detection unit 42. Among them, when the support plate portion 411 is of rigid structure, the fastener 43 locks and connects the detection unit 42 to the support plate portion 411. The positioning columns 413 cooperate with the detection unit 42 for positioning to accurately position the detection unit 42. The circuit board 421 is provided with positioning holes 4211, and the positioning columns 413 and the positioning holes 4211 are inserted and positioned.

[0038] The circuit board 421 extends out of the support plate portion 411, and the detection element 422 is spaced apart from the support plate portion 411, so that a detection space is formed between the detection element 422 and the support plate portion 411.

[0039] In a preferred embodiment, the support plate portion 411 is provided with a positioning groove 415, and the detection unit 42 is defined in the positioning groove 415. The positioning groove 415 is of groove structure, and the positioning columns 413 are arranged at the bottom of the positioning groove 415. The circuit board 421 is defined in the positioning groove 415, thus forming an assembly connection. Further, the positioning groove 415 and the buckle pins 412 are arranged back to back on the support plate portion 411. The detection unit 42 can be installed on the support plate portion 411 from the positioning groove 415, and the buckle pins 412 and the detection unit 42 are independently arranged, which is convenient for the disassembly and assembly of the detection unit 42.

[0040] As Figures 3 to 5 shown, the linear drive assembly 22 includes a switching motor 221 fixed to the housing 10 and a threaded sleeve 222 connected to the output shaft of the switching motor 221. The threaded sleeve 222 is helically connected to the mounting bracket 21. The switching motor 221 serves as a driving member of the power module 20. Among them, the switching motor 221 drives the threaded sleeve 222 to rotate forward or backward, and the mounting bracket 21 slides linearly back and forth along the housing 10 under the driving of the helical force of the threaded sleeve 222, so as to realize different moving distances and moving reversals. The switching motor 221 can be configured as a small motor to reduce the installation space and meet the driving force of the threaded sleeve 222.

[0042] The mounting bracket 21 slides on the machine shell 10. The mounting bracket 21 is provided with a trigger unit 211 for the induction detection element 422. The trigger unit 211 moves synchronously with the mounting bracket 21, and the detection element 422 is located on the moving path of the trigger unit 211. The detection element 422 is used to trigger the moving stroke of the mounting bracket 21 to form an automatic detection structure. The trigger unit 211 is arranged on the mounting bracket 21. During the movement of the mounting bracket 21, the trigger unit 211 moves within the detection area of the detection element 422. The detection element 422 and the trigger unit 211 can be set as an induction mechanism or a trigger mechanism. For example, the detection element 422 and the trigger unit 211 are set as a Hall induction mechanism, a travel switch trigger mechanism, or a photoelectric switch mechanism.

[0043] In one embodiment, there are two detection elements 422, and the trigger unit 211 of the power module 20 is arranged to move between the two detection elements 422. Specifically, the detection element 422 includes a first detection piece 4221 and a second detection piece 4222 which are spaced apart. The trigger unit 211 moves between the first detection piece 4221 and the second detection piece 4222. The first detection piece 4221 and the second detection piece 4222 are set as travel switches. The first detection piece 4221 is used to detect the extreme position of the first end of the movement of the mounting bracket 21, and the second detection piece 4222 is used to detect the extreme position of the second end of the movement of the mounting bracket 21. The first detection piece 4221 and the second detection piece 4222 send electrical signals to the control circuit of the switching motor 221, and the switching motor 221 controls the start and stop based on this electrical signal.
