fig. 1 shows a preferred embodiment of the quick release stand of the present invention, which includes a supporting frame 1, an assembling portion 2 supported by the supporting frame 1, and a fastener 3 disposed on the assembling 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 has an assembly slot 411, the assembly portion 2 can be assembled to the assembly slot 411 of the back case 41 or disassembled from the assembly slot 411, in this embodiment:

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

As shown in fig. 4, the assembling portion 2 includes a housing 21, which is generally made of plastic, and an assembling plate 22, which is generally made of iron. The housing 21 has a back plate 211, a plurality of side plates 212-215 respectively disposed on each side of the back plate 211 and protruding forward, and an opening 216 defined by the side plates 212-215. One of the side plates 212 has a side hole 217 therethrough, and the other side plate 213 is located opposite the one of the side plates 212. The assembling plate 22 is coupled to the housing 21 and covers the opening 216 of the housing 21, and the coupling manner can be selected from screwing, buckling or other manners. In addition, the assembling plate 22 further has a hook 221 extending forward, and as shown in fig. 1 and fig. 2, the hook 221 is adjacent to the other side plate 213 of the housing 21 and can hook into the hook hole 415 of the bottom wall 410 of the assembling slot 411. The number of hooks 221 corresponds to the number of hook holes 415, and preferably two hooks.

As shown in fig. 6, a user hooks the hook 221 of the assembly plate 22 of the assembly portion 2 into the hook hole 415 of the bottom wall 410 of the assembly slot 411, and then inserts the housing 21 of the assembly portion 2 into the assembly slot 411, thereby completing the assembly of the assembly portion 2 and the assembly slot 411, at this time, the side hole 217 of the assembly portion 2 overlaps the buckle hole 414 of the assembly slot 411, and the hook 221 hooks into the hook hole 415, so that the assembly portion 2 is temporarily fixed in the assembly slot 411 without falling out. However, since the fastener 3 is in an unbuckled state, the user can still remove the assembly portion 2 from the assembly slot 411 by a reverse operation.

As shown in fig. 4 and 5, the fastener 3 includes a moving block 31 disposed on the assembling portion 2 and capable of moving on the assembling portion 2, a hook block 32 connected to a first side 311 of the moving block 31, and the arched elastic piece 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 to each other, and the moving block 31 further has a front side 313 and a rear side 314. The hook blocks 32 move along with the movement of the moving block 31, and the number of the hook blocks 32 is preferably 2. The arched elastic piece 33 has two end portions 331 and an arched section 332 located between the two end portions 331, the two end portions 331 are separated by a distance and are respectively connected to the second side edge 312 of the moving block 31, a space 333 is formed between an inner side surface of the arched section 332 and the second side edge 312 of the moving block 31, and an outer side surface of the arched section 332 abuts against an abutting surface 218a on the back plate 211 of the housing 21 of the assembling portion 2. In this embodiment, the abutting surface 218a is a bottom side of a wall plate 218 on the back plate 211. The thickness of the arched elastic pieces 33 is preferably 0.7 to 1.2mm, and the distance between the two ends 331 of the arched elastic pieces 33 is equal to 1.5 to 2.5 times the distance between a vertex of the arched section 332 and the second side 312 of the moving block 31.

Fig. 6 and 7 show the fastening device 3 in the unfastened state, at this time, the moving block 31 is already located at an unfastened position shown in the figures, the hook block 32 is already separated from the fastening hole 414 in the assembling groove 411 and is retracted into the side hole 217 on the assembling portion 2, so that the assembling portion 2 is in a state of being detachable from the assembling groove 411, at this time, the assembling portion 2 can be easily detached from the assembling groove 411, and the purpose of quickly detaching the electronic device 4 from the quick detach stand of the present invention is achieved.

Fig. 8 and 9 show the fastening device 3 in a locked state, at this time, the moving block 31 is already located at a locked position shown in the figures, and the hook block 32 has already protruded out of the side hole 217 on the assembling portion 2 and entered into the locking hole 414 in the assembling slot 411, so that the assembling portion 2 is locked to the assembling slot 411 and is in a state of being unable to be detached, at this time, the fast assembly of the electronic device 4 and the fast-detachable stand of the present invention is completed.

Since the moving block 31 presses the arched elastic pieces 33 to deform during the movement process of the moving block from the locking position to the unlocking position, as shown in fig. 6 and 7, so that the arched elastic pieces 33 accumulate an elastic force due to the deformation, the moving block 31 will be rebounded to the locking position by the elastic force as long as the user releases the moving block 31. When the moving block 31 is located at the locking position, the arched elastic pieces 33 still provide a moderate elastic force under the support of the abutting surface 218a, so as to maintain the state of the moving block 31 located at the locking position, and ensure that the hook block 32 does not leave the locking hole 414 of the assembling slot 411 arbitrarily.

As is apparent from the above description, the moving block 31 of the retainer 3 can linearly reciprocate between the locking position and the unlocking position, and the hook block 32 that moves in synchronization with the moving block 31 can enter the locking hole 414 of the assembly groove 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, thereby determining whether the assembly portion 2 can be detached from the assembly groove. In addition, the structure of the fastener 3 is simple, so that the integrally formed fastener 3 is easily manufactured by plastic injection molding, in this embodiment, the fastener 3 is integrally formed by plastic material with elasticity, and the plastic material is preferably PC/ABS thermoplastic plastic.

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

Preferably, the front side 313 and the rear side 314 of the moving block 31 of the fastener 3 are respectively provided with 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 32 of the fastener 3 can move in the notch 222.

As shown in fig. 11, the electronic device 4 further includes a fixing plate 42 made of iron, the fixing plate 42 is fixed on the back shell 41 and located at the back of the assembling slot 411, and the fixing plate 42 has a through hole 421, and the through hole 421 is preferably two and overlaps the hook hole 415 of the back shell 41. As shown in fig. 6, the hook 221 of the assembly portion 2 not only hooks into the hook hole 415 of the back shell 41, but also hooks onto a back surface of the fixing plate 42 through the through hole 421 of the fixing plate 42.

As shown in fig. 4, the fastening device 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 hook block 32. Preferably, the magnet 34 is a slot 37 disposed on the hook block 32. In this embodiment, the hook blocks 32 are two and each has a slot 37 for receiving two magnets. Preferably, each hook 32 further has a small stop piece 38 facing the front side 313 of the moving block 31, and each magnet 34 has an exposed portion exposed from the receiving groove 37 of the hook 32, the exposed portion being sandwiched between the small stop piece 38 and the front side 313 of the moving block 31. As shown in fig. 9, the magnet 34 attracts the fixed plate 42 to ensure that the moving block 31 is reliably positioned at the locking position, and the hook block 32 is prevented from moving arbitrarily.

Preferably, as shown in fig. 6 and 9, the bottom wall 410 of the assembling slot 411 of the back shell 41 has a thick wall 416 and a thin wall 417 connected to each other at a position corresponding to the fastening member 3, the thick wall 416 faces the moving block 31, the thin wall 417 faces the magnet 34 on the hook block 32 and covers the moving range of the magnet 34, and a front end of the hook block 32 abuts against the thin wall 417 of the assembling slot 411. The thin wall 417 is thin, and therefore does not greatly affect the attraction force of the magnet 34 to the magnetic attachment plate 42.

In addition, as shown in fig. 12, the fixing plate 42 preferably further has a through hole 422, when the moving block 31 of the fastening device 3 is located at the releasing position, the through hole 422 is aligned with the magnet 34, so that the magnetic attraction force of the magnet 34 to the fixing plate 42 is weakened and the moving block 31 is easily released from the fixing plate 42, which is beneficial for the moving block 31 to smoothly return to the locking position from the releasing position, and reduces the load of the moving block 31 being pushed by the arched elastic piece 33.

In summary, the quick-release stand of the present invention can be quickly assembled to or disassembled from the electronic device 4, and has a simple structure, easy assembly and cost reduction, and particularly, the fastener 3 has a simple structure and is easy to be manufactured into an integrally formed structure by plastic injection. In addition, the fastener 3 also ensures that the moving block 31 is reliably positioned at the locking position by the arrangement of the magnet 34, and the hook block 32 is prevented from moving arbitrarily.

The present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof, and it should be understood that various changes and modifications can be effected therein by one skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims.
