[0040] The present invention provides a locking mechanism that can be used to fix a bracket of electronic equipment such as a projector, but is not limited here.

[0041] Reference Figures 1 to 3 In one embodiment of the present invention, the locking mechanism 100 includes a locking member 10, a transmission mechanism 20 and a manipulation component 30; the locking member 10 has a locking position and an unlocking position; when in the locking position, the locking member 10 is suitable for clamping the connector 200 of the electronic device; when in the unlocking position, the locking member 10 is suitable for disengaging from the connector 200 of the electronic device; the output end of the transmission mechanism 20 is connected to the locking member 10; the manipulation component 30 is connected to the input end of the transmission mechanism 20 and is used to drive the transmission mechanism 20 to move so as to drive the locking member 10 to switch between the locking position and the unlocking position.

[0042] This embodiment is described in detail using a projector as an example electronic device. A plate-shaped connector 200 is secured to the bottom of the projector via screws. The connector 200 has notches on its four sides for the locking member 10 to clamp / engage. Obviously, the locking members 10 of this embodiment can be a pair, or two or more pairs, preferably a pair, but this is not a limitation.

[0043] Specifically, in this embodiment, the locking member 10 may include two opposing clamping arms, at least one of which can be controlled to move by a manipulation component 30 to achieve free switching between a locked position and an unlocked position. The manipulation component 30 may be a knob 311, a button, or a lever, etc. The transmission mechanism 20 between the manipulation component 30 and the locking member 10 may employ a push-up structure, etc., and the specific structure can be designed according to the specific situation and is not limited here.

[0044] It can be understood that the present invention provides a locking member 10 and an operating member 30, and connects the operating member 30 to the locking member 10 through a transmission mechanism 20, thereby realizing free switching of the locking member 10 between a locked position and an unlocked position, that is, realizing a detachable locking connection between the locking mechanism 100 and the connecting member 200 of the electronic device. Moreover, since the locking member 10 locks the electronic device by clamping the connecting member 200, compared with the combination of the pin and the slot in the prior art, the connection between the locking mechanism 100 of the present invention and the electronic device is more stable and reliable, which greatly improves the reliability of the connection between the bracket and the electronic device.

[0045] Reference Figures 1 to 3 In one embodiment, the transmission mechanism 20 includes a rotating member 211, a movable member 212 and a reset member 213, the operating member 30 is a knob 311, and the locking mechanism 100 also includes a first shell 411 and a second shell 412 connected to the first shell 411. The knob 311 is screwed on the first shell 411 and sleeved on one end of the rotating member 211. The other end of the rotating member 211 is connected to the second shell 412 through a torsion member 312. The two movable members 212 are connected through a reset member 213. The two movable members 212 are respectively arranged on both sides of the rotating member 211 and abut against it. One end of the two locking members 10 is respectively arranged on the two movable members 212. Two limiting portions 313 are provided on the knob 311. The two movable members 212 are both provided with limiting grooves 212a adapted to the limiting portions 313. Two avoidance windows are opened on the second shell 412 to allow the free ends of the two locking members 10 to pass through. Such a configuration can further improve the reliability of the locking mechanism 100 in connecting to the electronic device, and the operation is relatively simple. When in use, it is only necessary to rotate the knob 311 to unlock it, and it will automatically reset to the locked position when you release it.

[0046] When the knob 311 is rotated, the rotating member 211 rotates and drives the two movable members 212 to move in opposite directions, so that the locking member 10 retracts and moves to the unlocking position, the torsion member 312 is twisted and compressed, and the reset member 213 is stretched.

[0047] When the force applied to the knob 311 is released, the torsion piece 312 and the reset piece 213 restore their deformations, and the reset piece 213 resets and drives the two movable pieces 212 to move toward each other, so that the locking piece 10 extends and moves to the locked position. The torsion piece 312 resets and drives the knob 311 and the limiting portion 313 thereon, and the limiting portion 313 moves into the limiting groove 212a, restricting the movement of the movable piece 212, so that the locking piece 10 remains in the locked position.

[0048] In order to further enhance the stability of the connection between the locking mechanism 100 and the connector 200 of the electronic device, in this embodiment, the locking member 10 uses two plug plates, which are relatively arranged on the two movable members 212 and form an acute angle with the opening facing the rotating member 211.

[0049] In this embodiment, a connecting shaft is provided at one end of each plugboard. The movable member 212 is provided with two mounting slots 212b that are arranged opposite each other and extend along the height direction of the movable member 212. The ends of the connecting shaft are movably disposed within the two mounting slots 212b. This arrangement not only effectively expands the opening and closing range of the two plugboard clamps, meeting the requirements for securing the connector 200 of electronic devices of various specifications, but also reduces operator effort and allows the plugboard to be securely clamped to both sides of the connector 200.

[0050] Preferably, the limiting groove 212 a of this embodiment can be an arc-shaped notch formed on the movable member 212 , so that the movable member 212 can be stably maintained in the locked state.

[0051] Furthermore, in order to enable the movable member 212 to move more smoothly and thus enable the locking member 10 to move smoothly between the locked position and the unlocked position, the outer contour of the abutment between the rotating member 211 and the movable member 212 of this embodiment can be set to an involute arc.

[0052] Reference Figures 4 to 7 In another embodiment, the transmission mechanism 20 includes two push members 221, the control component 30 is a rotary cover 321, and both push members 221 are mounted on the rotary cover 321. The locking mechanism 100 also includes a protective shell 421. One end of each locking member 10 is rotatably mounted on the inner side of the protective shell 421, and a torsion spring 121 is sleeved around the rotation axis of each locking member. The protective shell 421 has a clearance opening for allowing the other ends of the two locking members 10 to pass through. The locking members 10 are each provided with an arcuate groove 10a adapted to fit the push members 221. The rotary cover 321 is screwed onto the protective shell 421, and a return torsion spring 322 is sleeved around the rotation axis of the rotary cover 321. The transmission mechanism 20 of this embodiment has a simpler structure, fewer parts, a smaller size, easier assembly, and lower cost.

[0053] When the rotary cover 321 is rotated, the two pushing members 221 move in their respective corresponding arc-shaped grooves 10 a, causing the locking member 10 to rotate and retract to the unlocking position, and the return torsion spring 322 is twisted and compressed, and the torsion spring 121 is twisted and compressed.

[0054] When the force applied to the rotary cover 321 is released, the reset torsion spring 322 recovers its deformation, driving the rotary cover 321 and the two push members 221 thereon to return to their original position. The torsion spring 121 recovers its deformation, causing the locking member 10 to return to its original position and extend to the locked position.

[0055] To ensure the stability of the locking mechanism 100 in locking the connector 200 of the electronic device, in this embodiment, a blocking portion can be provided on the locking member 10. When in the locked position, the blocking portion abuts against the inner wall of the protective shell 421 to maintain the locking member 10 in the locked position.

[0056] In this embodiment, the locking member 10 may preferably be in a petal shape, which can effectively ensure that it clamps the connecting member 200 more tightly when in the locked position, thereby helping to enhance the connection reliability.

[0057] In this embodiment, the pushing member 221 and the rotating cover 321 can be integrally formed to further save the manufacturing cost of the product.

[0058] The present invention also proposes a bracket, which includes a locking mechanism 100. The specific structure of the locking mechanism 100 refers to the above embodiment. Since the bracket proposed by the present invention includes all schemes of all embodiments of the above locking mechanism 100, it has at least the same technical effect as the locking mechanism 100, which will not be elaborated here one by one.

[0059] The above description is merely an optional embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by utilizing the contents of the present invention specification and drawings under the inventive concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
