[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] The opening and closing of traditional vehicle hatches usually rely on the vehicle body's electronic system. This control method can effectively ensure the safety and convenience of the vehicle in most cases. However, in certain emergencies, the control system of this electric hatch will not work properly, resulting in the hatch being unable to open and close normally, which will cause great inconvenience and safety risks to the driver and passengers.

[0040] To solve the defects of the above electric hatch during use, please refer to Figure 1-Figure 5The present invention provides a manual drive device for locking and unlocking a vehicle hatch, which can realize the opening and closing control of the hatch through a manual drive mechanism when the electric mode fails. The drive device is based on a base plate 1. Both sides of the top of the base plate 1 are rotatably installed with swing arms 2 with two control modes, which are electric control mode and manual control mode. A connecting frame 3 is fixed to the end of the swing arm 2, and a hatch body 4 is fixed to the end of the connecting frame 3. The hatch body 4 can be opened and closed electrically or manually controlled by the swing arm 2. The two swing arms 2 are controlled separately. When an unexpected situation occurs in one hatch body 4, it will not affect the opening and closing of the other hatch body 4. An electric drive mechanism 5 and a manual drive mechanism 6 acting on the swing arm 2 are also provided on the base plate 1. The electric drive mechanism 5 and the manual drive mechanism 6 are respectively arranged on both sides of the swing arm 2. The driving mechanism 5 includes a hydraulic rod 51 fixedly mounted on the top of the base plate 1 and a connecting rod 52 rotatably mounted on the bottom of the swing arm 2. A switching member 53 for switching the two control modes of the swing arm 2 is provided between the hydraulic rod 51 and the connecting rod 52. Under normal circumstances, driving the hydraulic rod 51 can pull the swing arm 2 to swing through the connecting rod 52, and the swinging of the swing arm 2 can drive the door body 4 to open and close. This is an electric mode. When the electric mode cannot be used, the connection between the swing arm 2 and the hydraulic rod 51 can be disconnected through the switching member 53. Subsequently, the manual driving mechanism 6 can be used to manually control the rotation of the swing arm 2, so that the door body 4 can still be opened and closed smoothly in an emergency, thereby enhancing the equipment's ability to cope with emergencies.

[0041] In order to achieve the manual control effect of the above-mentioned manual drive mechanism 6 on the swing arm 2, the manual drive mechanism 6 is set to a slide 61 fixedly installed on the top of the base plate 1, and the internal sliding connection of the slide 61 is provided with an adjusting block 62, and the top of the adjusting block 62 is rotatably connected with a push rod 63. The end of the push rod 63 is rotatably installed on one side of the swing arm 2, and a pair of card joints 64 are installed at both ends of the adjusting block 62. A through hole 65 is provided at the end of the slide 61 for the card joint 64 to pass through. A handle is also installed on the top of the adjusting block 62. Pulling the handle can drive the adjusting block 62 to slide, and the sliding of the adjusting block 62 can drive the push rod 63 to rotate. The rotation of the push rod 63 can push and pull the hatch body 4, thereby controlling the opening and closing of the hatch body 4.

[0042] In manual mode, when the swing arm 2 drives the hatch body 4 to be in the open and closed state, the adjusting block 62 needs to be fixed to prevent the adjusting block 62 from driving the hatch body 4 to slide. Therefore, the end of the base plate 1 is also provided with a limit piece for fixing the card joint 64. The limit piece includes a frame 661 symmetrically installed on the end of the slide 61, and a lifting rod 662 is installed between the two frames 661 to slide up and down. A limiting column 663 is installed on the side of the lifting rod 662 close to the card joint 64. A circular hole is opened on the card joint 64 to match the limiting column 663, and connecting springs 664 are installed at both ends of the lifting rod 662. The end of the connecting spring 664 is fixedly installed on the inner wall of the frame 661. When the hatch body 4 is in the closed or open state, the card joint 64 will pass through one end of the slide 61, and the lifting rod 662 can slide up and down to drive the limiting column 663 to enter the circular hole of the card joint 64, thereby limiting the sliding of the adjusting block 62, thereby preventing the hatch body 4 from opening and closing automatically.

[0043] In order to facilitate the control of the entry and exit of the limiting column 663 in the circular hole, an extrusion block 665 with a trapezoidal cross section is installed between the two frames 661 for sliding back and forth. A roller 666 is installed on the side of the lifting rod 662 close to the extrusion block 665. The roller 666 contacts the extrusion block 665. A fixing rod 667 is fixed between the two frames 661. The internal thread of the fixing rod 667 is connected to a threaded rod 668. The end of the threaded rod 668 is rotatably installed on the extrusion block 665. The top and bottom of the extrusion block 665 are both provided with slopes. In the natural state, the limiting column 663 passes By the elastic force of the connecting spring 664 away from the round hole, even if the swing arm 2 is in the electric mode, the limit column 663 will not affect the control of the electric drive mechanism 5 on the opening and closing of the hatch body 4. In manual mode, when the adjustment block 62 runs to one end of the slide 61, the threaded rod 668 can be rotated to drive the extrusion block 665 to slide back and forth, and the extrusion block 665 squeezes the roller 666 to slide toward the card joint 64. The lifting rod 662 can push the limit column 663 into the card joint 64 to achieve manual locking of the adjustment block 62, so that the hatch body 4 can be fixed in the open or closed position.

[0044] Since the connection between the swing arm 2 and the hydraulic rod 51 needs to be disconnected before the manual drive mechanism 6 is used to control the swing arm 2, the switching member 53 is set as a clamping frame 531 fixedly installed on the output end of the hydraulic rod 51, and the end of the connecting rod 52 is installed in the clamping frame 531. The clamping frame 531 is symmetrically provided with through holes 532, and an insert block 533 is inserted into the inside of the through hole 532. The connecting rod 52 is provided with a slot 534 adapted to the insert block 533, and a clamping groove 535 is provided on the side of one end of the insert block 533 extending to the slot 534, and the connecting rod 52 is provided with a clamping groove 535. A groove 536 is provided on it, and a slider 537 that is adapted to the slot 535 is slidably connected inside the groove 536. The slider 537 is inserted into the slot 535 to limit the insertion block 533, and the insertion block 533 is inserted into the through-hole 532 and the slot 534 to fix the card frame 531 on the connecting rod 52, so that the force of the hydraulic rod 51 can act on the swing arm 2. When the swing arm 2 is switched to manual mode, it is necessary to control the slider 537 to slide out of the slot 535, and then take out the insertion block 533 to separate the connecting rod 52 and the card frame 531.

[0045] In order to facilitate the control of the slider 537 to be inserted into the slot 535 and to slide out of the slot 535, a handle 538 is rotatably installed inside the groove 536, and a connecting rod 539 is rotatably installed on the top side of the handle 538. The end of the connecting rod 539 is rotatably installed on the slider 537. Rotating the handle 538 can drive the connecting rod 539 to swing, and the swinging of the connecting rod 539 can drive the slider 537 to slide. In this way, the switching between manual mode and electric mode can be achieved by simply rotating the handle 538.

[0046] In order to prevent malicious human rotation of the turning handle 538, a hexagonal slot 5310 is opened at the center position of the top of the connecting rod 539, and an anti-touch cover 5311 is installed on the connecting rod 52 to cover the turning handle 538. A protective plug corresponding to the hexagonal slot 5310 is movably installed on the anti-touch cover 5311. The anti-touch cover 5311 is used to protect the turning handle 538. When rotating the turning handle 538, it is necessary to open the protective plug first, and then use a special hexagonal wrench to turn the turning handle 538 to prevent the card frame 531 and the connecting rod 52 from falling off accidentally, thereby improving the safety of the equipment.

[0047] When the locking cam 73 is unlocked, the locking cam 73 is unlocked and the locking cam 73 is unlocked, so that the master cam 73 can be unlocked and the master cam 73 can be unlocked.

[0048] In order to enhance the smoothness of opening and closing of the hatch body 4, a guide rail 8 is also installed on the top of the base plate 1, and the bottom of the swing arm 2 is installed on a track plate 9 adapted to the guide rail 8. A plurality of evenly distributed balls 10 are installed for rotation inside the track plate 9. The balls 10 are in contact with the guide rail 8. The balls 10 can enhance the smoothness of the swinging of the swing arm 2, thereby improving the smoothness of opening and closing of the hatch body 4.

[0049] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by a person skilled in the art. The provision of power is also common knowledge in the art. The present invention is mainly used to protect mechanical devices, so the control method and circuit connection are not explained in detail in the present invention.
