Detailed Description

The structural and operational principles of the present invention are described in detail below with reference to the accompanying drawings:

fig. 1 shows a preferred embodiment of the quick-release stand of the present invention, which comprises a support frame 1, an assembly portion 2 supported by the support frame 1, and a fastener 3 disposed on the assembly portion 2. As shown in fig. 2, the quick-release stand is suitable for supporting an electronic device 4, such as a computer screen or a television screen, but not limited thereto. The electronic device 4 includes a back case 41, the back case 41 having an assembling slot 411, the assembling portion 2 being capable of being assembled to the assembling slot 411 of the back case 41 or being detached from the assembling slot 411, in this embodiment:

as shown in fig. 2 and 3, the assembly slot 411 on the back shell 41 has a bottom wall 410, a first side wall 412 vertically connected to the bottom wall 410 and opposite to each other, a fastening hole 414 penetrating the first side wall 412, and a hook hole 415 penetrating the bottom wall 410 and adjacent to the second side wall 413. Wherein, the number of the hook holes 415 is preferably two.

As shown in fig. 4, the assembly part 2 comprises a housing 21, typically made of plastic, and an assembly plate 22, typically made of iron. The housing 21 has a back plate 211, a plurality of side plates 212 to 215 respectively provided on respective sides of the back plate 211 and protruding forward, and an opening 216 defined by the side plates 212 to 215. One of the side plates 212 has a side hole 217 therethrough, and the other side plate 213 is located opposite to the one of the side plates 212. The assembly plate 22 is coupled to the housing 21 and covers the opening 216 of the housing 21, and the coupling may be threaded, snap-fit, or otherwise. In addition, the assembly plate 22 further has a hook 221 extending forward, and as shown in fig. 1 and 2, the hook 221 is adjacent to the other side plate 213 of the housing 21 and can be hooked into the hook hole 415 of the bottom wall 410 of the assembly slot 411. The number of hooks 221 corresponds to the number of hook holes 415, preferably two.

As shown in fig. 6, a user hooks the hooks 221 on the assembly plate 22 of the assembly part 2 into the hook holes 415 of the bottom wall 410 of the assembly slot 411, and plugs the housing 21 of the assembly part 2 into the assembly slot 411 in order to complete the assembly of the assembly part 2 and the assembly slot 411, at this time, the side holes 217 on the assembly part 2 overlap the hook holes 414 in the assembly slot 411, and the assembly part 2 is temporarily fixed in the assembly slot 411 without falling out at will by the hooks 221 hooking into the hook holes 415. However, since the fastener 3 is in a unfastened state at this time, the user can still detach the assembly part 2 from the assembly slot 411 under the reverse operation.

As shown in fig. 4 and 5, the fastener 3 includes a moving block 31 disposed on the assembly portion 2 and capable of moving on the assembly portion 2, a hook block 32 connected to a first side 311 of the moving block 31, and an arch spring 33 connected to a second side 312 of the moving block 31. The first side 311 and the second side 312 of the moving block 31 are opposite, and the moving block 31 further has a front side 313 and a rear side 314. The hook blocks 32 move with the movement of the moving block 31, and the number of the hook blocks 32 is preferably 2. The arch spring 33 has two ends 331 and an arch section 332 between the two ends 331, the two ends 331 are spaced apart and connected to the second side 312 of the moving block 31, a space 333 is formed between an inner surface of the arch section 332 and the second side 312 of the moving block 31, and an outer surface of the arch section 332 abuts against an abutment surface 218a on the back plate 211 of the housing 21 of the assembly part 2. In this embodiment, the abutment surface 218a is a bottom side of a wall plate 218 on the back plate 211. The thickness of the arch spring 33 is preferably 0.7 to 1.2mm, and the distance between the two ends 331 of the arch spring 33 is equal to 1.5 to 2.5 times the distance between an apex of the arch segment 332 and the second side 312 of the moving block 31.

Fig. 6 and 7 show the fastener 3 in the unbuckled state, at this time, the moving block 31 is already located at an unbuckled position shown in the drawing, and the hook 32 is already separated from the fastening hole 414 in the assembly slot 411 and retracted into the side hole 217 on the assembly part 2, so that the assembly part 2 is in a state of being detachable from the assembly slot 411, and at this time, the assembly part 2 can be easily detached from the assembly slot 411, thereby achieving the purpose of quickly detaching the electronic device 4 from the quick-release stand of the present invention.

Fig. 8 and 9 show the fastener 3 in a locked state, at this time, the moving block 31 is already located at a locked position shown in the drawing, and the hook block 32 is already extended out of the side hole 217 of the assembly part 2 and enters into the locking hole 414 in the assembly slot 411, so that the assembly part 2 is locked in the assembly slot 411 and is in a state of being unable to be detached, and at this time, the quick assembly of the electronic device 4 and the quick-release stand of the invention is completed.

Since the movable block 31 is deformed by pressing the dome-shaped spring plate 33 during the movement of the movable block 31 from the locking position to the unlocking position, as shown in fig. 6 and 7, the dome-shaped spring plate 33 accumulates a spring force due to the deformation, so that the movable block 31 is bounced back to the locking position due to the spring force as long as the user releases the movable block 31. When the moving block 31 is located at the locking position, the arched spring plate 33 still provides a moderate elastic force under the support of the abutting surface 218a, so as to keep the moving block 31 in the locking position, and ensure that the hook block 32 cannot be arbitrarily separated from the locking hole 414 of the assembling slot 411.

As can be seen from the above description, the moving block 31 of the fastener 3 can linearly reciprocate between the locking position and the unlocking position, and the hook 32 moving synchronously with the moving block 31 can enter the locking hole 414 of the assembling slot 411 when the moving block 31 reaches the locking position, and can be disengaged from the locking hole 414 when the moving block 31 reaches the unlocking position, so as to determine whether the assembling portion 2 can be detached from the assembling slot. In addition, because the fastener 3 has a simple structure, the fastener 3 is easy to be manufactured in an integral molding manner by plastic injection, and in this embodiment, the fastener 3 is integrally molded by elastic plastic material, and the plastic material is preferably PC/ABS thermoplastic.

As further shown in fig. 4 and 5, to facilitate the user pushing the moving block 31 of the fastener 3, the fastener 3 further includes a pushing portion 35, where the pushing portion 35 is connected to the rear side 314 of the moving block 31 and is exposed to a window 219 on the back plate 21 of the assembly portion 2. In this embodiment, the pushing portion 35 is a push button, but not limited thereto, for example, the pushing portion 35a shown in fig. 10 is a groove, and a tool 351 (for example, a screwdriver) is used to push a sidewall of the groove, so that the moving block 31 can be pushed.

Preferably, the front side 313 and the rear side 314 of the moving block 31 of the fastener 3 also have a plurality of ribs 36 parallel to the moving direction, so as to reduce the contact area between the moving block 31 and the assembling plate 22 and the back plate 210 of the assembling portion 2, and reduce the resistance during moving.

Preferably, as shown in fig. 4, the assembling plate 22 of the assembling portion 2 further has a notch 222, the notch 222 is communicated with the side hole 217 of the housing 21, and the hook block 32 of the fastener 3 can move in the notch 222.

As shown in fig. 11, the electronic device 4 further generally includes a fixing plate 42 made of iron, wherein the fixing plate 42 is fixed on the back shell 41 and located at the back of the assembly slot 411, and the fixing plate 42 has through holes 421, and the through holes 421 are preferably two and overlap with the hook holes 415 of the back shell 41. As shown in fig. 6, the hook 221 on the assembly part 2 is hooked on a back surface of the fixing plate 42 not only in the hook hole 415 of the back shell 41, but also through the through hole 421 of the fixing plate 42.

As shown in fig. 4, the fastener 3 further includes a magnet 34 capable of magnetically attracting the fixing plate 42, and the magnet 34 may be disposed on the moving block 31 or the hooking block 32. Preferably, the magnet 34 is a receptacle 37 provided on the hooking block 32. In this embodiment, the hook block 32 has two hooks and each has a receiving slot 37 for two magnets. More preferably, each hooking block 32 also has a small blocking piece 38 facing the front side 313 of the moving block 31, and each magnet 34 has an exposed portion exposed from the containing groove 37 of the hooking block 32, the exposed portion being sandwiched between the small blocking piece 38 and the front side 313 of the moving block 31. As shown in fig. 9, the moving block 31 is positioned at the locking position by the attraction force of the magnet 34 to the fixing plate 42, so as to ensure that the hooking block 32 does not move arbitrarily.

Preferably, as shown in fig. 6 and 9, the bottom wall 410 of the assembly slot 411 of the back shell 41 has a thick wall 416 and a thin wall 417 connected to each other corresponding to the fastener 3, the thick wall 416 faces the moving block 31, the thin wall 417 faces the magnet 34 on the hook 32 and covers the moving range of the magnet 34, and a front end of the hook 32 abuts against the thin wall 417 of the assembly slot 411. Since the thin wall 417 is thin, the attraction force to the magnet 34 and the attraction fixing plate 42 is not greatly affected.

In addition, as shown in fig. 12, the fixed plate 42 preferably further has a hole 422 passing therethrough, when the movable block 31 of the fastener 3 is located at the releasing position, the hole 422 is opposite to the magnet 34, so that the magnetic attraction force of the magnet 34 to the fixed plate 42 is weakened and is easy to release from the fixed plate 42, which is beneficial to smoothly returning the movable block 31 from the releasing position to the locking position, and reduces the load of the arched spring 33 for rebounding and pushing the movable block 31.

In summary, the quick-release stand of the present invention not only can be quickly assembled to or disassembled from the electronic device 4, but also has a simple structure, easy assembly, and low cost, and particularly, the fastener 3 has a simple structure and is easy to manufacture an integrally formed structure by plastic injection. In addition, the fastener 3 further ensures that the moving block 31 is positioned at the locking position by the arrangement of the magnet 34, so that the hook block 32 cannot move arbitrarily.

Of course, the present invention is capable of other various embodiments and its several details are capable of modification and variation in light of the present invention, as will be apparent to those skilled in the art, without departing from the spirit and scope of the invention as defined in the appended claims.
