A torsion spring is fixedly connected to one end of the rotating column. A rotating block is rotatably connected to the other side of the installation shell. The rotating block is fixedly connected to the other end of the torsion spring. A connecting shaft is fixedly connected to one end of the rotating block. A lock is fixedly connected to the other end of the rotating column. The lock engages with the lock hook.

[0009] Furthermore, two mounting rods are fixedly connected to the top of one side of the fixing frame, and pneumatic and electric support rods are rotatably connected to the bottom of the mounting rods.

[0010] Based on the aforementioned scheme, a rotating shaft is rotatably connected between the inner walls of both sides of the fixed frame, and a support shaft is fixedly connected to the outer wall of one side of the rotating shaft. One end of the pneumatic strut and one end of the electric strut are rotatably connected to the support shaft.

[0011] As a further embodiment of the present invention, two fixed seats are fixedly connected to one side of the inner wall of the hatch, and the other end of the support shaft is rotatably connected to the fixed seats.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, the present invention provides an electric strut type luggage compartment opening mechanism, which has the following advantages:

[0018] 1. The present invention, through the setting of locking disc and electric buckle, when the hatch is locked with the secondary lock, the locking disc is engaged with the electric buckle. At the same time, the wire rope stops tightening, so that the lock hook and the buckle are kept engaged, and the wire rope is not kept constantly tightened, thus preventing the hatch from being pulled inward continuously, thereby avoiding the deformation of the sealing strip and the hatch.

[0019] 2. This invention uses a connecting shaft to rotate, which in turn drives the rotating block to rotate. Under the action of a torsion spring, the rotating column rotates, which in turn drives the latch to rotate, thereby separating the latch from the latch hook. This allows the hatch to be opened manually, thus avoiding the embarrassing situation of the hatch being unable to be opened.

[0020] 3. This invention, through the coordinated arrangement of pneumatic struts, electric struts, and support shafts, can fully control the rising and closing motion of the cabin door, eliminating the need for large air cylinders, simplifying the structure, and greatly improving the space utilization of the luggage compartment.

[0021] 4. The present invention can strengthen the hatch by setting a reinforcing rib on one side of the hatch, thereby improving the impact resistance of the hatch and thus better protecting the items in the luggage compartment. Attached Figure Description

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Reference Figures 1-6 An electric strut type luggage compartment opening mechanism includes a fixed frame 1 and a door 10. Two mounting blocks 11 are fixed to one side of the fixed frame 1 by bolts. A connecting plate 13 is provided on one side of the mounting block 11. Two fixing bolts 14 are threadedly connected to one side of the mounting block 11 and one side of the connecting plate 13. A first fixing plate 15 is inserted into one side of the connecting plate 13. A locking hook 16 is fixed to one side of the first fixing plate 15 by bolts. A slot 19 is provided on one side of the first fixing plate 15. A first locking post 20 is locked in the slot 19. A steel wire rope 21 is fixed to the outer wall of the first locking post 20. Two return springs 28 are fixed to one side of the first fixing plate 15 by bolts. A second fixing plate 17 is fixed to the other side of the connecting plate 13 by bolts. The other end of the return spring 28 is fixedly connected to the second fixing plate 17. A rope sleeve 18 is fixed to one side of the second fixing plate 17 by bolts. The rope sleeve 18 protects the steel wire rope 21, and the steel wire rope 21 passes through the rope sleeve 18.

[0031] A motor 23 is bolted to one side of the second fixed plate 17. A rotating gear 24 is keyed to one end of the output shaft of the motor 23. A rotating disk 25 is engaged with one side of the rotating gear 24. Two positioning pins 26 are integrally formed on one side of the rotating disk 25. A locking disk 27 is sleeved between the two positioning pins 26. A second locking pin 22 is engaged with one side of the locking disk 27. The other end of the steel wire rope 21 is fixedly connected to the second locking pin 22. An electric latch 29 is bolted to one side of the second fixed plate 17. The electric latch 29 engages with the locking disk 27. It should be noted that the electric latch 29 engages with the protruding part of the locking disk 27. A protective shell 12 is bolted to one side of the inner wall of the hatch 10. A mounting shell 30 is bolted to one side of the inner wall of the protective shell 12. A rotating column 31 is inserted into one side of the mounting shell 30. A torsion spring 32 is bolted to one end of the rotating column 31. A rotating column 31 is bolted to the other side of the mounting shell 30. A rotating locking block 33 is connected to the rotating locking block 33, which is fixedly connected to the other end of the torsion spring 32. The torsion spring 32 facilitates the reset of the rotating locking block 33. One end of the rotating locking block 33 is fixed to a connecting shaft by bolts, and the other end of the rotating column 31 is keyed to a latch 34. The latch 34 engages with the latch hook 16. Driven by the motor 23, the rotating gear 24 rotates, thereby driving the rotating disk 25 and the locking disk 27 to rotate, which tightens the wire rope 21 and pulls the first fixed plate 15 to move towards the side of the locking disk 27. This causes the latch hook 16 to engage with the latch 34, thereby locking the secondary lock of the hatch 10. At this time, the locking disk 27 also engages with the electric latch 29. At the same time, the wire rope 21 stops tightening, so that the latch hook 16 and the latch 34 remain engaged, and the wire rope 21 is not kept constantly tightened, thus preventing the hatch 10 from being pulled inward continuously.

[0032] Two mounting rods 2 are bolted to the top of one side of the fixed frame 1. A pneumatic strut 3 and an electric strut 4 are rotatably connected to the bottom of the mounting rods 2. A rotating shaft 5 is rotatably connected between the inner walls of both sides of the fixed frame 1. A support shaft 6 is welded to the outer wall of one side of the rotating shaft 5. One end of the pneumatic strut 3 and one end of the electric strut 4 are rotatably connected to the support shaft 6. Two fixing seats 7 are bolted to the inner wall of one side of the hatch 10. The other end of the support shaft 6 is rotatably connected to the fixing seats 7. When the pneumatic strut 3 and the electric strut 4 are activated, the rotating shaft 5 and the support shaft 6 rotate under their influence. This allows the hatch 10 to close onto the vehicle body. Two support rods 9 are rotatably connected to one side of the inner wall of the hatch 10. Two mounting seats 8 are fixed to one side of the fixing frame 1 by bolts. The support rods 9 support the opening and closing of the hatch 10. The other end of the support rods 9 is rotatably connected to the mounting seats 8. A reinforcing rib 35 is welded to one side of the inner wall of the hatch 10 to improve the impact resistance of the hatch 10. A manual handle 36 is provided on one side of the outer wall of the hatch 10. The other end of the connecting shaft passes through the hatch 10 and is fixedly connected to the manual handle 36. An anti-slip sleeve is fitted on the outer wall of the manual handle 36 to facilitate the rotation of the connecting shaft.

[0033] The working principle of this embodiment is as follows: In use, first, connect the power supply and the external controller. When it is necessary to close the hatch 10, activate the pneumatic strut 3 and the electric strut 4. Driven by the pneumatic strut 3 and the electric strut 4, the rotating shaft 5 and the support shaft 6 rotate, causing the hatch 10 to close onto the vehicle body. Then, start the motor 23. Driven by the motor 23, the rotating gear 24 rotates, causing the rotating disk 25 and the locking disk 27 to rotate. This tightens the wire rope 21, pulling the first fixing plate 15 towards one side of the locking disk 27. This causes the locking hook 16 to engage with the locking buckle 34, thus securing the hatch 10. When the lock is engaged, the locking disc 27 also engages with the electric latch 29. At the same time, the wire rope 21 stops tightening, thus keeping the lock hook 16 engaged with the latch 34. This prevents the wire rope 21 from being constantly tightened, thus preventing the hatch 10 from being pulled inward continuously. When the pneumatic strut 3 and the electric strut 4 fail, the manual handle 36 is pulled to rotate the connecting shaft, which in turn rotates the rotating block 33. Under the action of the torsion spring 32, the rotating column 31 rotates, which in turn rotates the latch 34, causing the latch 34 to separate from the lock hook 16, thus manually opening the hatch 10.
