[0005] Preferably, the detachable rotary drive assembly includes a second rotating shaft disposed within the drive housing body. Both ends of the second rotating shaft are connected to the inner wall of the drive housing body via first bearings. Two first bevel gears are fixedly connected and sleeved on the outside of the second rotating shaft. One end of a worm gear is fixedly connected to the second bevel gear located within the drive housing body. A second bearing is provided at the connection between the worm gear and the drive housing body. The second bevel gear meshes with the first bevel gear.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] (1) The first insert and the third rotating shaft are driven to rotate by a single-axis motor, and then the fourth bevel gear and the second rotating shaft are driven to rotate by the third bevel gear. The two first bevel gears are driven to rotate by the second rotating shaft, and then the second bevel gear drives the worm to rotate, which in turn drives the worm wheel and the first rotating shaft to rotate, so that the box door can rotate relative to the cargo box, and thus the opening and closing of the box door can be completed automatically.

[0017] (2) Manually drive the movable plate away from the first fixed plate to move the second insert block away from the insertion hole.

[0018] (3) When the box door is closed, the box door contacts one side of the cargo box, the locking block is inserted into the groove, and the box door and the switch are in contact. The switch controls the single-axis motor to stop, the box door stops rotating, and the switch controls the dual-axis motor, so that the dual-axis motor drives the two lead screws to rotate, thereby causing the two adjacent movable seats to move away from each other, so that the locking block is inserted into the slot, limiting the position of the box door and preventing the box door from opening. Through the design of the guide block and guide groove, the movable seat slides smoothly in the horizontal direction. Through the design of the support plate and the sixth bearing, the possibility of lead screw wobbling is reduced. When the box door contacts the switch, it can be known that the box door is in the closed state. Real-time detection of the box door can reveal the opening and closing status of the box door, which is convenient for actual use.

[0019] (4) The design of the fourth rotating shaft, the second fixed plate and the fourth bearing enables the door to rotate relative to the cargo box. The design of the third fixed plate and the fifth bearing enables the first rotating shaft to rotate relative to the cargo box, thereby increasing the stability of the first rotating shaft when it rotates.

Through the design of the third fixed plate 37 and the fifth bearing 38, the first rotating shaft 8 is rotatably connected relative to the cargo box 1, which increases the stability of the first rotating shaft 8 when rotating.

[0036] Example 4, based on Example 2, by Figure 1 , Figure 3 , Figure 5 and Figure 9 The opposite drive mechanism includes a dual-axis motor 40 fixedly mounted on the inner wall of the slide 3. Two lead screws 41 are fixedly connected to the two output ends of the dual-axis motor 40. The two lead screws 41 pass through two movable seats 39 respectively. The threads on adjacent lead screws 41 are in opposite directions. The movable seats 39 and lead screws 41 are connected by threads. Two guide grooves 42 are formed on the inner wall of the slide 3. A guide block 43 is fixedly connected to the movable seat 39 and is located within the guide groove 42.

[0037] When the door 2 is closed, it contacts one side of the cargo box 1. The locking block 7 is inserted into the groove 5, and the door 2 contacts the switch 4. The switch 4 controls the single-axis motor 22 to stop, and the door 2 stops rotating. The switch 4 also controls the dual-axis motor 40, which drives the two lead screws 41 to rotate, thereby causing the two adjacent movable seats 39 to move away from each other. This allows the locking block 7 to be inserted into the slot 6, limiting the position of the door 2 and preventing it from opening. The design of the guide block 43 and the guide groove 42 allows the movable seat 39 to slide smoothly in the horizontal direction. The design of the support plate 44 and the sixth bearing 45 reduces the possibility of the lead screw 41 shaking. When the door 2 contacts the switch 4, it can be known that the door 2 is in a closed state. Real-time detection of the door 2 can reveal its open / closed status, improving handling efficiency and facilitating practical use.

[0038] Working principle: During operation, the single-axis motor 22 drives the first insert block 23 and the third rotating shaft 17 to rotate, which in turn drives the fourth bevel gear 20 and the second rotating shaft 12 to rotate via the third bevel gear 18. The second rotating shaft 12 drives the two first bevel gears 14 to rotate, which in turn drives the worm gear 11 to rotate via the second bevel gear 15. This causes the worm gear 11 to drive the worm wheel 9 and the first rotating shaft 8 to rotate, allowing the door 2 to rotate relative to the cargo box 1, thus enabling the door 2 to open and close. The movable plate is manually driven. 31 moves away from the first fixing plate 25, causing the second insert 30 to disengage from the insertion hole 28. The tension spring 32 is in a stretched state, releasing the restriction on the position of the limiting plate 26. The manually driven mounting base 21 moves away from the drive box body 10, causing the single-axis motor 22 to drive the first insert 23 to disengage from the slot 24, and the limiting plate 26 to disengage from the limiting groove 27. This completes the removal of the single-axis motor 22. When the box door 2 is closed, the box door 2 contacts one side of the cargo box 1, the locking block 7 is inserted into the groove 5, and the box door 2 and the opening... When switch 4 contacts the door, it stops the single-axis motor 22, causing the door 2 to stop rotating. Switch 4 also controls the dual-axis motor 40, which drives the two lead screws 41 to rotate. This causes the two adjacent movable seats 39 to move away from each other, allowing the locking block 7 to insert into the locking slot 6, limiting the position of the door 2 and preventing it from opening. The guide block 43 and guide groove 42 allow the movable seats 39 to slide smoothly in the horizontal direction. The support plate 44 and the sixth bearing 45 reduce the possibility of the lead screw 41 wobbling. When the door 2 contacts the switch 4, it indicates that the door 2 is in a closed state. Real-time detection of the door 2 allows for monitoring its open / closed status, improving handling efficiency and facilitating practical use. The fourth rotating shaft 34, the second fixed plate 35, and the fourth bearing 36 allow the door 2 to rotate relative to the cargo box 1. The third fixed plate 37 and the fifth bearing 38 allow the first rotating shaft 8 to rotate relative to the cargo box 1, increasing the stability of the first rotating shaft 8 during rotation.
