[0038] The lifting rod 32 has a vertical rod body 321 and a horizontal rod body 322. The vertical rod body 321 is protruding from the top of the top wall 313 of the casing 31. The horizontal rod body 322 is formed at the top of the vertical rod body 321. The lifting rod 32 and the casing 31 jointly define a first wiring channel 33. The first wiring channel 33 is used to accommodate at least one or more wires (not shown). Specifically, the first wiring channel 33 of the present embodiment extends along the first horizontal direction X. The lifting rod 32 is in an inverted L shape. The vertical rod body 321 of the lifting rod 32 is adjacent to and above the corresponding side wall 311 of the casing 31 for abutting against the side panel 123, and the vertical rod body 321 is used to abut against the side panel 123, thereby making the first wiring channel Page 6 / 11

[0039] The volume of the first wiring channel 33 can be maximized so as to provide more wire accommodation. The first wiring channel 33 has two first end openings 331 spaced apart along the first horizontal direction X, and a first side opening 332 between the first end openings 331. The first end opening 331 is used for the wire to pass through. The first side opening 332 is used for the wire to pass through, so that the wire can be installed in the first wiring channel 33 from the external environment or moved away from the first wiring channel 33, thereby improving the convenience of wire disassembly and assembly. In addition, the vertical rod body 321 has a vertical stop surface 323. The cross rod body 322 has a horizontal stop surface 324 connected to the vertical stop surface 323, and a first force-bearing surface 325 opposite to the horizontal stop surface 324. The first force-bearing surface 325 is used for the user's finger pressing operation. On the other hand, the lifting rod 32 also has a positioning column 326 protruding from the outside of the vertical rod body 321. The positioning column 326 is used to engage in the corresponding positioning hole 125. The vertical rod body 321 is formed with a receiving hole 327 . The receiving hole 327 is used to correspond to the position of another through hole 124 .

[0040] The nuts 7 are fixedly disposed in the receiving holes 317 and 327 , respectively. Each screw 8 is used to pass through the corresponding through hole 124 and be screwed to the corresponding nut 7 , so as to lock the docking kit 3 to the side plate 123 .

[0041] See also Figure 2 , Figure 3 , Figure 4 and Figure 5 The locking member 4 can be movably disposed on the frame 121 of the first electronic component 120 to be locked to the positioning column 2, so as to lock the first electronic component 120 to the second electronic component 130. In this embodiment, the locking member 4 can be rotatably pivoted to the shaft member 5, so that the locking member 4 can be rotatably disposed on the frame 121 of the first electronic component 120 through the docking kit 3 and the shaft member 5.

[0042] The locking member 4 is a single component made of, for example, a plastic material by injection molding. The locking member 4 has a buckle rod 41 and an operating rod 42. The buckle rod 41 is a lever for being accommodated in the accommodating space 319 and pivoted to the shaft member 5. The buckle rod 41 is formed with a pivot hole 410 for the shaft member 5 to pass through and is pivoted to the shaft member 5. The buckle rod 41 has a lower rod body 411, a buckle portion 412, an upper rod body 413, and a support column 414. The lower rod body 411 is located at the lower half of the pivot hole 410 and has a first end 415 for facing the docking kit 3, and a second end 416 opposite to the first end 415. The first end 415 and the second end 416 are spaced apart along the first horizontal direction X. The buckle portion 412 is plate-shaped and formed at the bottom end of the lower rod body 411 and is located below the shaft member 5. The buckle portion 412 protrudes out of the first end 415 and has a free end 417 facing backward and spaced from the first end 415. The buckle portion 412 is formed with a buckle groove 418 that is recessed from the free end 417 toward the first end 415 and is used to buckle with the neck 22. The top surface of the buckle portion 412 extends downward and tilted toward the first end 415 to form a chamfered surface 419. The chamfered surface 419 is semicircular and surrounds the end of the buckle groove 418. The chamfered surface 419 is used to abut against the annular bottom surface 212 of the head 21 in a surface contact manner and can be stopped by the annular bottom surface 212. The top surface of the buckle portion 412 is recessed downward and toward the first end 415 to form a semicircular oblique groove 420 that is connected to the end of the buckle groove 418. The chamfered surface 419 is located at the bottom of the semicircular oblique groove 420. The semicircular arc-shaped oblique groove 420 can provide a portion of the bottom end of the head 21 of the positioning column 2 for accommodating. The upper rod 413 is connected to the top of the lower rod 411 and is located at the upper half of the pivot hole 410. The upper rod 413 is hollow. The support 414 is disposed in the upper rod 413.

[0043] The operating rod 42 is inclined and has an inclined rod body 421 and an unlocking portion 422. The inclined rod body 421 is protruding from the top of the upper rod body 413 of the buckle rod 41. The unlocking portion 422 is plate-shaped and formed at the top of the inclined rod body 421 and is located above the shaft 5. The operating rod 42 and the buckle rod 41 jointly define a second wiring channel 43. The second wiring channel 43 is used to accommodate at least one or more wires. Specifically, the second wiring channel 43 of this embodiment extends along the first horizontal direction X. The second wiring channel 43 corresponds to the first wiring channel 33 and is arranged along the first horizontal direction X. The operating rod 42 is in an inverted L shape. The inclined rod body 421 of the operating rod 42 is adjacent to one side of the upper rod body 413 of the buckle rod 41. The inclined rod body 421 of the operating rod 42 is also protruding from one side of the upper rod body 413 of the buckle rod 41 and corresponds to the position of the vertical rod body 321 of the lifting rod 32, thereby maximizing the volume of the second wiring channel 43 and providing more wire accommodation. The second wiring channel 43 has two second end openings 431 spaced apart along the first horizontal direction X, and a second side opening 432 between the second end openings 431. The second end opening 431 is used for the wire to pass through. The second side opening 432 is used for the wire to pass through, so that the wire can be installed in the second wiring channel 43 from the external environment or moved away from the second wiring channel 43, thereby improving the operational convenience of wire disassembly and assembly. In addition, the inclined rod body 421 has a first inclined stop surface 423 for the vertical stop surface 323 to stop. The unlocking portion 422 has a second oblique stop surface 424 for being stopped by the horizontal stop surface 324 , and a second force-bearing surface 425 opposite to the second oblique stop surface 424 .

[0044] The second force-bearing surface 425 is used for pressing operation by a user's finger.

[0045] The locking member 4 can be locked around the shaft member 5 relative to the docking assembly 3 at the locking portion 412 to a locking position (such as Figure 8 ), and the buckle portion 412 is separated from a release position of the neck 22 (as shown in Fig. 9 The second force-bearing surface 425 of the unlocking portion 422 is used for pressing by the user's finger, so that the locking member 4 can rotate from the locking position to the releasing position to make the buckle portion 412 detach from the neck 22.

[0046] See also Figure 3 , Figure 4 and Figure 6 The elastic member 6 is used to be arranged on the docking kit 3 and the locking member.

[0047] 4. The elastic member 6 is configured to apply elastic force to the locking member 4 so that the locking member 4 is kept in the locked position where the buckle portion 412 is buckled on the neck 22, and the elastic member 6 is also configured to be deformed by the locking member 4 when the unlocking portion 422 is operated to make the buckle portion 412 detach from the neck 22. In this embodiment, the elastic member 6 is an example of a compression spring but is not limited thereto. The elastic member 6 is used to be sleeved on the pillar 315 of the docking kit 3 and the pillar 414 of the locking member 4. The two ends of the elastic member 6 are used to abut against the upper rod 413 of the docking kit 3 and the locking member 4, respectively.

[0048] See also Figure 2 , Figure 3 , Figure 4 and Figure 6 When the components of the locking mechanism 140 are to be assembled together and assembled to the frame 121, the positioning columns 314 and 326 of the docking kit 3 are first aligned with the positioning holes 125 of the side plate 123. Then, the docking kit 3 is placed against the side plate 123 so that the positioning columns 314 and 326 are respectively engaged with the positioning holes 125. Each screw 8 is inserted into the corresponding through hole 124 and screwed into the corresponding nut 7 to lock the docking kit 3 to the side plate 123. Next, the elastic member 6 is accommodated in the accommodation space 319 of the docking kit 3, so that one end of the elastic member 6 is sleeved on the pillar 315. After that, a part of the buckle rod 41 of the locking member 4 is accommodated in the accommodation space 319 of the docking kit 3, so that the pivot hole 410 is connected between the shaft holes 316, and the other end of the elastic member 6 is sleeved on the pillar 414. At this time, the buckle portion 412 of the locking member 4 is located below the sleeve 312 of the docking kit 3. Finally, the shaft 5 is inserted into the shaft hole 316 of the docking kit 3 and the pivot hole 410 of the locking member 4, and the assembly between the components of the locking mechanism 140 and the assembly between the locking mechanism 140 and the frame 121 is completed. Since the number of components of the locking mechanism 140 is small, the assembly process between the components and between the components and the frame 121 is simple and convenient. The assembled structure of the locking mechanism 140 is simple and small in size, which can easily reduce the occupied space and manufacturing cost.

[0049] See also Figure 2 , Figure 6 and Figure 7When the first electronic component 120 is to be assembled to the second electronic component 130, first, the frame 121 of the first electronic component 120 is aligned with the housing 110 so that the first electronic component 120 is located above the position to be assembled. At this time, the limiting hole 318 of the docking kit 3 is aligned above the head 21 of the positioning column 2. Next, the first electronic component 120 is moved downward, and the first electronic component 120 will simultaneously drive the locking mechanism 140 to move downward. During the downward movement of the locking mechanism 140, the head 21 of the positioning column 2 will first extend into the buckle groove 418 of the buckle portion 412, so that the buckle portion 412 first contacts the guide cone 211 of the head 21. The lateral thrust applied by the guide cone 211 to the buckle portion 412 will open the buckle portion 412, so that the locking member 4 rotates relative to the docking kit 3 around the shaft 5 along a first rotation direction R1. During the rotation of the locking member 4 along the first rotation direction R1, the upper rod body 413 of the buckle rod 41 will squeeze the elastic member 6 and drive the elastic member 6 to move toward the docking kit 3, so that the elastic member 6 is compressed and deformed and accumulates the restoring elastic force. Subsequently, the head 21 of the positioning column 2 will extend into the limiting hole 318 of the sleeve 312. When the frame 3 has a position deviation on the two-dimensional plane jointly formed by the first horizontal direction X and the second horizontal direction Y, the sleeve 312 will contact the guide cone 211 of the head 21 and slide downward along the guide cone 211. The sleeve 312 will be gradually corrected by the guide cone 211, so that the head 21 can be smoothly inserted into the limiting hole 318. When the buckle portion 412 moves away from the guide cone 211, the locking member 4 stops rotating. After that, the docking kit 3 and the locking member 4 will continue to move downward relative to the positioning column 2.

[0050] See also Figure 7 and Figure 8 When the buckle portion 412 of the locking member 4 moves downward to a position separated from the head 21, the restoring elastic force accumulated by the elastic member 6 is applied to the upper rod 413 and the upper rod 413 rebounds, so that the locking member 4 rotates relative to the docking kit 3 around the shaft 5 in a second rotation direction R2 opposite to the first rotation direction R1. At the same time, the docking circuit board 122 of the first electronic component 120 is docked with the second electronic component 130. When the locking member 4 rotates to the locking position where the buckle groove 418 of the buckle portion 412 is buckled with the neck 22 of the positioning column 2, the locking member 4 no longer rotates, so that the locking member 4 automatically locks the positioning column 2. In this way, the locking mechanism 140 automatically locks the first electronic component 120 to the second electronic component 130.

[0051] The elastic member 6 applies elastic force to the upper rod 413 of the locking member 4, so that the locking member 4 is always kept in the locking position where the buckle groove 418 of the buckle portion 412 is buckled on the neck 22. In this way, the locking member 4 can be firmly locked on the positioning column 2 to prevent the locking member 4 from being easily separated from the neck 22 of the positioning column 2 due to vibration or external force. In addition, when the locking member 4 is in the locking position, the operating rod 42 of the locking member 4 is separated from the lifting rod 32 of the docking kit 3, and an angle A is formed between the operating rod 42 and the lifting rod 32.

[0052] See also Fig. 9 and Fig.10 When the first electronic component 120 is to be removed from the second electronic component 130, the user first applies force with two fingers to press the first force-bearing surface 325 of the crossbar body 322 of the docking kit 3 and the second force-bearing surface 425 of the unlocking portion 422 of the locking member 4. Since the locking member 4 is pivotally connected to the shaft member 5, the second force-bearing surface 425 will cause the locking member 4 to rotate relative to the docking kit 3 around the shaft member 5 along the first rotation direction R1 when the force is applied. During the rotation of the locking member 4 along the first rotation direction R1, the buckle groove 418 of the buckle portion 412 will gradually disengage from the neck 22 of the positioning column 2, the operating rod 42 will gradually approach the lifting rod 32 of the docking kit 3, and the elastic member 6 will be squeezed and deformed by the upper rod body 413 of the buckle rod 41.

[0053] When the first oblique stop surface 423 of the oblique rod body 421 is stopped by the vertical stop surface 323 and the unlocking part

[0054] When the second oblique stop surface 424 of the locking member 422 is stopped by the horizontal stop surface 324, the locking member 4 is limited by the lifting rod 32 at the release position where the buckle groove 418 of the buckle portion 412 is completely separated from the neck 22, so that the locking member 4 is unlocked. Subsequently, the first force-bearing surface 325 of the crossbar body 322 and the second force-bearing surface 425 of the unlocking portion 422 are pulled upward, and the pulling force drives the locking mechanism 140 to move upward and is transmitted to the frame 121 through the locking mechanism 140 to lift the first electronic component 120 upward. When the limiting hole 318 of the sleeve 312 of the docking kit 3 moves away from the head 21 of the positioning column 2, and the docking circuit board 122 of the first electronic component 120 is separated from the second electronic component 130, the disassembly of the first electronic component 120 is completed.

[0055] By means of the vertical stop surface 323 and the horizontal stop surface 324 blocking the first oblique stop surface 423 and the second oblique stop surface 424 respectively, the blocking area of ​​the docking kit 3 blocking the locking member 4 is large, thereby improving the stability of the docking kit 3 blocking the locking member 4. In addition, due to the operation of applying force to press the first force-bearing surface 325 and the second force-bearing surface 425 and pulling the above two upwards, the locking member 4 can be rotated to the release position to release the locking state, and then the first electronic component 120 is lifted upward by the lifting rod 32 and the operating rod 42 that are abutted against each other to form a stable lifting structure to remove the first electronic component 120, so that the user can conveniently and quickly complete the unlocking operation of the locking member 4 and the disassembly operation of the first electronic component 120 in sequence. Since the above-mentioned operation is ergonomic and has fewer steps, the convenience, speed and efficiency of the user in the unlocking and disassembly operations can be improved.

[0056] See also Figure 8 When the frame 3 is subjected to an external force parallel to the vertical direction Z and upward, the external force will be transmitted to the docking kit 3 and pull the shaft 5 upward. Since the shaft 5 and the chamfered surface 419 of the buckle portion 412 are spaced apart in the first horizontal direction X, when the external force passes through the shaft 5, a force in the first rotation direction R1 (such as Figure 7 The aforementioned torque causes the annular bottom surface 212 to apply a reaction force opposite to the external force to the buckle portion 412. The aforementioned reaction force causes the chamfered surface 419 to rotate toward the annular bottom surface 212. When the chamfered surface 419 turns horizontally and abuts against the annular bottom surface 212 by surface contact, the chamfered surface 419 is stopped by the annular bottom surface 212 and reaches a balanced immobile state, so that the buckle groove 418 of the locking member 4 is still buckled in the neck 22 of the positioning column 2 and will not be separated from the neck 22. In this way, the locking member 4 will not be easily unlocked due to the external force generated by falling or improper operation, thereby improving the stability of the locking.

[0057] It should be noted that the locking mechanism 140 of this embodiment may also have the following different implementations depending on the needs:

[0058] In one implementation, the lifting rod 32 of the docking kit 3 is configured to stop the first oblique stop surface 423 of the oblique rod body 421 through the vertical stop surface 323 of the vertical rod body 321.

[0059] Another implementation: The lifting rod 32 of the docking kit 3 is configured to block the second oblique stop surface 424 of the unlocking portion 422 through the transverse stop surface 324 of the cross bar body 322.

[0060] To summarize the above, the locking mechanism 140 of this embodiment has a small number of components, so the assembly process between the components and between the components and the frame 121 is simple and convenient. The assembled structure of the locking mechanism 140 is simple and small in size, which can easily reduce the occupied space and manufacturing cost. The locking member 4 and the docking kit 3 of the locking mechanism 140 can provide automatic locking and blind insertion functions respectively, which can improve the convenience, speed and efficiency of assembly and locking operations. By applying force to press the first force-bearing surface 325 and the second force-bearing surface 425 and pull the above two upwards, the unlocking operation of the locking member 4 and the disassembly operation of the first electronic component 120 can be completed in sequence, which can improve the convenience, speed and efficiency of the unlocking and disassembly operations, and can indeed achieve the purpose of the utility model.
