[0053] Embodiment 3

[0054] On the basis of the first and second embodiments, this embodiment further describes the structure of the opening and closing device in detail.

[0055] The opening and closing device also includes a bracket 400 having a hollow cavity and a slider 600 fixedly connected to the connecting member 900. The peripheral wall of the hollow cavity is penetrated with a first hole 410. The slider 600 can slide along the first hole 410 to drive the connecting member 900 to perform lifting and lowering movements in the hollow cavity. The first hole 410 can limit the movement trajectory and maximum movement displacement of the slider 600 to achieve the purpose of limiting the movement trajectory and maximum movement displacement of the connecting member 900. In the embodiment of the present application, the slider 600 includes but is not limited to a bayonet, and the user can select according to actual needs, and no specific limitation is made here.

[0056] Furthermore, a second hole is provided on the peripheral wall of the hollow cavity for one end of the opening and closing component 300 to pass through and enter the hollow cavity. The second hole is used to limit the opening and closing component 300 to move only in a straight line, and to limit the maximum displacement of the straight line movement to prevent the opening and closing component 300 from moving out of the hollow cavity as a whole. In the embodiment of the present application, the opening and closing component 300 is two opening and closing bayonet pins arranged opposite to each other, and the end of the opening and closing bayonet pin close to the connecting member 900 enters the hollow cavity through the second hole, and the end of the opening and closing bayonet pin away from the connecting member 900 is connected to the movable member 220. As a preferred embodiment, a card slot is also provided on the movable member 220, and the opening and closing bayonet pin is used to clamp the connecting member 900 through the card slot. In addition, the bracket 400 is also used to install the transmission component 200. Specifically, the transmission component 200 is sleeved and fixed on the bracket 400. Such a design can make the structure of the entire device more compact.

[0057] The opening and closing device further includes a base 500, which is connected to the bracket 400 to support the bracket 400. A third hole is formed through the base 500, and the connecting member 900 passes through the third hole and enters the hollow cavity of the bracket 400. In the embodiment of the present application, the base 500 is disc-shaped, and the bracket 400 is connected at the center of the base 500.

[0058] The driving assembly 100 includes a driving gear 120 and a driving unit 110 that drives the driving gear 120 to rotate. The transmission assembly 200 includes a follower 210 meshing with the driving gear 120, and the follower 210 is connected to the opening and closing assembly 300. The follower 210 converts the rotation of the driving gear 120 into its own linear motion, and then drives the opening and closing assembly 300 to perform linear motion. As a preferred embodiment, the driving unit 110 is a servo motor with a function of stopping when reaching the maximum displacement. This type of servo motor can provide a more reliable stopping function and can quickly stop the motor movement in an emergency to protect the safety of the system and the operator. In the embodiment of the present application, the driving gear 120 is installed on the driving shaft of the servo motor, and the servo motor can drive the driving gear 120 to rotate.

[0059] In a specific embodiment, the driven member 210 is a driven gear, which is sleeved and fixed on the bracket 400. The driven gear is provided with an eccentric groove 230 eccentric to the rotation axis of the driven gear. Specifically, the driven gear has a top surface close to the opening and closing component 300 and a bottom surface far away from the closing component 300. The eccentric groove runs through the top and bottom surfaces of the driven gear and is arranged on the driven gear. The driven member also includes a movable member 220, one end of which is connected to the opening and closing component 300 and the other end is inserted into the eccentric groove 230 and can move in the eccentric groove 230. The driving gear 120 drives the driven gear to rotate, and the rotation of the driven gear causes the groove wall of the eccentric groove 230 to apply force to the movable member 220, so that the movable member 220 moves linearly to drive the opening and closing component 300 to move linearly.

[0060] As a preferred embodiment, the movable member 220 is a cam follower, one end of the cam follower close to the driven gear is connected to the opening and closing assembly 300, and one end of the cam follower away from the driven gear is inserted into the eccentric groove 230 and can move in the eccentric groove 230. Due to the restrictions of the opening and closing assembly 300 and the groove wall of the eccentric groove 230, the cam follower has a linear component in the opening and closing direction of the opening and closing assembly 300, or the cam follower can only perform linear motion in the opening and closing direction of the opening and closing assembly 300.

[0061] The shape, angle and length of the eccentric groove 230 affect the maximum displacement of the cam follower and thus the maximum displacement of the opening and closing assembly 300. In the embodiment of the present application, the eccentric groove 230 is arc-shaped. When the cam follower slides toward the rotation axis close to the driven gear, the cam follower drives the opening and closing assembly 300 to close, thereby achieving the jamming of the connecting member 900. When the cam follower slides away from the rotation axis of the driven gear, the cam follower drives the opening and closing assembly 300 to open, thereby achieving the loosening of the connecting member 900. The number of eccentric grooves 230 can be multiple, and the multiple eccentric grooves 230 are arranged along the circumference of the driven gear. In the embodiment of the present application, the number of eccentric grooves 230 and cam followers are two respectively, and the two cam followers are slidably limited in the two eccentric grooves 230 respectively.

[0062] In another specific embodiment, the driven member 210 may be a rack, which is disposed on the base 500. The rotation of the driving gear 120 drives the rack to move linearly to drive the opening and closing assembly 300 to move linearly. In this case, the linear movement of the opening and closing assembly 300 can be achieved only by the driving unit 110, the driving gear 120 and the rack, so the production cost of the device can be further reduced.

[0063] Furthermore, the opening and closing device also includes a first support plate 710, a second support plate 720 and a fixed plate 730. The first support plate 710 and the second support plate 720 are arranged opposite to each other, and the ends of the first support plate 710 and the second support plate 720 close to the base 500 are connected to the base 500, and the ends of the first support plate 710 and the second support plate 720 away from the base 500 are connected to the fixed plate 730, and the end of the driving unit 110 close to the driving gear 120 is connected to the fixed plate 730.

[0064] Furthermore, the opening and closing device also includes a deep groove ball bearing 810 and a bearing cover 820, which are respectively mounted on the bracket 400, the deep groove ball bearing 810 is arranged at one end close to the opening and closing component 300, the bearing cover 820 is arranged at one end far away from the closing component 300, and the follower 210 is arranged on the deep groove ball bearing 810.

[0065] The opening and closing device further includes a circlip 830, which is disposed on an end surface of the deep groove ball bearing 810 close to the bearing gland 820. The circlip 830 can prevent the bearing gland 820 and the deep groove ball bearing 810 on the bracket 400 from axial movement, which can improve the mechanical assembly accuracy, reduce assembly time, and play a role in shock absorption, buffering and preventing parts from loosening.
