[0051] The present embodiment provides an automatic locking and unlocking device for a gas strut, which is used to automatically lock the gas strut 100 and automatically unlock the gas strut 100 after marking the gas strut 100, so as to replace the steps of manually fixing and disassembling the gas strut 100, thereby reducing the time of manual operation and improving work efficiency.

[0052] like Figure 1 and Figure 2As shown, the present embodiment first briefly introduces the structure of the gas strut 100. The gas strut 100 includes a rod portion 101 and a head portion 102 disposed at one end of the rod portion 101. The head portion 102 has a ball socket 103. Two limit rods 104 are spaced apart in the ball socket 103.

[0053] like Figure 3 and Figure 4 As shown, the automatic locking and unlocking device of the gas strut provided in this embodiment includes a bracket 1, a first support plate 2, a locking assembly 3, a rotary drive assembly 4, a pressing assembly 5 and a lifting mechanism 6. The bracket 1 serves as a supporting component for other components and provides installation space for other components. The first support plate 2 is arranged on the bracket 1, and is used to support the rod 101 of the gas strut 100. Preferably, in order to improve the stability of the gas strut 100 after being placed on the first support plate 2, a receiving groove 21 is arranged at the upper end of the first support plate 2, and the receiving groove 21 is used to accommodate the rod 101. The receiving groove 21 can not only realize the rapid positioning of the gas strut 100, but also limit the rolling of the gas strut 100. The pressing assembly 5 is arranged on one side of the locking assembly 3, and is used to press down the head 102 of the gas strut 100 so that the ball socket 103 of the head 102 is inserted into the locking assembly 3. The locking assembly 3 is rotatably arranged on the bracket 1, and can be rotated to a locking position for locking the head 102 of the gas strut 100 and to an unlocking position for unlocking the head 102. The rotation drive assembly 4 is connected to the locking assembly 3, and can drive the locking assembly 3 to rotate to a locking position and an unlocking position. The lifting mechanism 6 is arranged on the bracket 1, and can drive the gas strut 100 to move upward, so that the ball socket 103 is separated from the locking assembly 3. The locking assembly 3, the lifting mechanism 6 and the first support plate 2 are arranged at intervals along the first direction.

[0054] In this embodiment, in order to make the locking assembly 3 quickly disengage from the ball socket 103, the lifting mechanism 6 is located on the side of the first support plate 2 close to the locking assembly 3. In order to make the automatic locking and unlocking device of the gas strut cooperate with other equipment, a preset distance needs to be maintained between the lifting mechanism 6 and the first support plate 2. In order to improve the fixing stability of the lifting mechanism 6, a pad 10 is provided between the lifting mechanism 6 and the first support plate 2, and the pad 10 is connected to both the lifting mechanism 6 and the first support plate 2.

[0055] Preferably, the lifting mechanism 6 includes a second driving member 61 and a lifting block 63. The second driving member 61 is arranged on the bracket 1. The lifting block 63 is connected to the output end of the second driving member 61. The second driving member 61 can drive the lifting block 63 to reciprocate in the vertical direction. When locking the gas strut 100, the lifting block 63 is in a lower avoidance position, so as not to affect the downward movement of the gas strut 100, so that the locking assembly 3 is inserted into the ball socket 103. When unlocking the gas strut 100, the second driving member 61 drives the lifting block 63 to move upward, ejecting the rod 101 from the receiving groove 21 and ejecting the head 102 from the locking assembly 3, so as to realize the unloading of the gas strut 100.

[0056] In order to push the gas strut 100 that has been released from the accommodating groove 21 and the locking assembly 3 away from the gas strut automatic locking and unlocking device to achieve automatic unloading of the gas strut 100, the bracket 1 is also provided with a second support plate 7 located on one side of the jacking mechanism 6, and the jacking mechanism 6 also includes an ejection assembly.

[0057] The lifting block 63 includes a support plate 631 and a vertical plate 632, and the support plate 631 is used to receive the rod 101. The second support plate 7 and the vertical plate 632 are spaced apart along the second direction, and the side of the second support plate 7 close to the vertical plate 632 is a guide surface. The vertical plate 632 is provided with a receiving hole, and the ejection assembly is inserted into the receiving hole. The lifting block 63 moves upward, and the guide surface can drive the ejection assembly to slide along the second direction, so that the ejection assembly abuts against the rod 101 and drives the rod 101 to move along the second direction, thereby disengaging the gas strut 100 from the gas strut automatic locking and unlocking device. In this embodiment, the first direction is perpendicular to the second direction.

[0058] like Figure 6 As shown, specifically, the guide surface includes a vertical surface 71 and an inclined surface 72 , the inclined surface 72 is connected to the upper end of the vertical surface 71 , and the inclined surface 72 is inclined from bottom to top toward a direction gradually approaching the vertical plate 632 .

[0059] During the process of the rod 101 being ejected from the accommodating groove 21 and the head 102 being ejected from the locking assembly 3, one end of the ejection assembly abuts against the vertical surface 71, and the ejection assembly does not slide in the second direction; after the rod 101 is ejected from the accommodating groove 21 and the head 102 is ejected from the locking assembly 3, the ejection assembly moves upward until it abuts against the inclined surface 72. As the ejection assembly continues to move upward, the inclined surface 72 drives the ejection assembly to slide in the second direction and in the direction close to the gas strut 100, gradually pushing the gas strut 100 away from the gas strut automatic locking and unlocking device.

[0060] like Figure 5As shown, in order to enable the ejection assembly to automatically reset when the lifting block 63 moves from top to bottom to a position opposite to the vertical surface 71, the ejection assembly includes a push rod 64 and a spring 62. The push rod 64 is slidably inserted into the receiving hole, one end of the push rod 64 abuts against the guide surface, and the other end passes through the receiving hole. A retaining ring 641 is provided on the push rod 64, and the spring 62 is sleeved on the push rod 64, one end of the spring 62 abuts against the retaining ring 641, and the other end abuts against the vertical plate 632. When the lifting block 63 moves to a position opposite to the inclined surface 72, the spring 62 is in a compressed state, so that when the lifting block 63 descends to a position opposite to the vertical surface 71, the ejection assembly can automatically reset.

[0061] like Figure 3 and Figure 5 As shown, the locking assembly 3 includes a rotating shaft 31 and a locking block 32, the rotating shaft 31 is rotatably arranged on the bracket 1, the locking block 32 is connected to the upper end of the rotating shaft 31, the locking block 32 can be inserted into the ball socket 103, and can be rotated to a locking position and an unlocking position. Preferably, the locking block 32 is a drum-shaped structure, the rotating shaft 31 is connected to the peripheral surface of the drum-shaped structure, and the maximum diameter of the drum-shaped structure is greater than the spacing between the two limiting rods 104. When the two end faces of the drum-shaped structure face the two limiting rods 104 of the gas strut 100, the locking block 32 can be inserted into the ball socket 103, and when the two end faces of the drum-shaped structure are at an angle of 90° with the length direction of the limiting rod 104, the drum-shaped structure is located between the two limiting rods 104, thereby limiting the locking block 32 from being separated from the ball socket 103. Of course, in other embodiments, the locking block 32 can also be a rectangular parallelepiped structure.

[0062] In order to support the rotating shaft 31 , a base 33 may be further provided on the bracket 1 . A blind hole is provided on the base 33 . The rotating shaft 31 is rotatably connected to the base 33 via a bearing.

[0063] The rotation drive assembly 4 includes a first drive member 41 and a connecting portion 42. The first drive member 41 is disposed on the bracket 1. In this embodiment, the first drive member 41 is connected to the base 33 via a connecting plate 43. One end of the connecting portion 42 is hinged to the output end of the first drive member 41, and the other end is hinged to the locking assembly 3. The output end of the first drive member 41 can be extended and retracted to drive the locking assembly 3 to rotate back and forth.

[0064] The pressing assembly 5 includes a third driving member 51 and a pressing head 52. The pressing head 52 is connected to the output end of the third driving member 51 and is used to press the head 102. In this embodiment, the first driving member 41, the second driving member 61 and the third driving member 51 can be cylinders or oil cylinders.

[0065] In order to automatically detect whether the gas strut automatic locking and unlocking device has a gas strut 100 placed therein, the gas strut automatic locking and unlocking device further comprises a photoelectric sensor 8, which is disposed on the first support plate 2. Specifically, a mounting frame 9 is disposed on one side of the first support plate 2 away from the lifting mechanism 6, and the photoelectric sensor 8 is fixed on the mounting frame 9.

[0066] The automatic locking process of the gas strut automatic locking and unlocking device provided in this embodiment is as follows:

[0067] The gas strut 100 is placed on the first support plate 2 by a robot or manually, and the ball socket 103 of the head 102 is arranged opposite to the locking assembly 3, and the locking assembly 3 is in the unlocked position;

[0068] The pressing component 5 presses down the head 102 so that the locking component 3 is inserted into the ball socket 103;

[0069] The rotation drive assembly 4 drives the locking assembly 3 to rotate to the locking position, and the pressing assembly 5 returns to the initial position, thereby completing the automatic locking of the gas strut 100 .

[0070] The unlocking and unloading process of the gas strut automatic locking and unlocking device provided in this embodiment is as follows:

[0071] The rotation drive assembly 4 drives the locking assembly 3 to rotate to the unlocking position;

[0072] The second driving member 61 drives the lifting block 63 to rise, and one end of the lifting rod 64 abuts against the vertical surface 71. The lifting mechanism 6 pushes the gas strut 100 upward, and pushes the rod portion 101 out of the receiving groove 21 and the head portion 102 out of the locking assembly 3. The lifting rod 64 rises until one end thereof abuts against the inclined surface 72.

[0073] The second driving member 61 continues to drive the lifting block 63 to rise, and the push rod 64 slides towards the gas strut 100 under the action of the inclined surface 72, and the other end of the push rod 64 abuts against the gas strut 100, and drives the gas strut 100 to move away from the vertical plate 632 until the gas strut 100 is pushed away from the gas strut automatic locking and unlocking device;

[0074] The second driving member 61 drives the lifting block 63 to descend to the initial position, and the lifting rod 64 abuts against the vertical surface 71 under the action of the elastic force of the spring 62 .
