[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0039] The opening and closing of traditional vehicle hatches usually rely on the operation of the body electronic system. This control method can effectively ensure the safety and convenience of the vehicle in most cases. However, in some emergency situations, 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 above defects of the 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, and swing arms 2 with two control modes are rotatably installed on both sides of the top of the base plate 1. The two control modes are electric control mode and manual control mode. A connecting frame 3 is fixedly connected to the end of the swing arm 2, and a hatch body 4 is fixedly connected 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, and the two swing arms 2 are controlled separately. When an unexpected situation occurs to 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 installed on the top of the base plate 1 and a connecting rod 52 rotatably installed on the bottom of the swing arm 2. A switching member 53 for switching the two control modes of the swing arm 2 is arranged 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 swing of the swing arm 2 can drive the door body 4 to open and close. This is the 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 smoothly opened and closed in an emergency, thereby enhancing the ability of the equipment to cope with emergencies.

[0041] In order to achieve the manual control effect of the manual driving mechanism 6 on the swing arm 2, the manual driving mechanism 6 is set to a slide 61 fixedly installed on the top of the base plate 1, and the inside of the slide 61 is slidably connected with an adjusting block 62, and a push rod 63 is rotatably connected to the top of the adjusting block 62. 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 for the card joint 64 to pass through is opened at the end of the slide 61. 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 the manual mode, when the swing arm 2 drives the hatch body 4 to be in the state of opening and closing, the adjustment block 62 needs to be fixed to prevent the adjustment block 62 from driving the hatch body 4 to slide. Therefore, a limiter 66 for fixing the card joint 64 is also provided at the end of the bottom plate 1. The limiter 66 includes a frame 661 symmetrically installed at the end of the slide 61. A lifting rod 662 is installed between the two frames 661 to slide up and down. A limit column 663 is installed on the side of the lifting rod 662 close to the card joint 64. A circular hole matched with the limit column 663 is provided on the joint 64, and connecting springs 664 are installed at both ends of the lifting rod 662. The ends of the connecting springs 664 are fixedly installed on the inner wall of the frame 661. When the hatch body 4 is in a 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 limit column 663 to enter the circular hole of the card joint 64, so as to limit the sliding of the adjustment 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, and a roller 666 is installed on the side of the lifting rod 662 close to the extrusion block 665, and the roller 666 is in contact with the extrusion block 665. A fixing rod 667 is fixed between the two frames 661, and the internal thread of the fixing rod 667 is connected with a threaded rod 668, and 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 connecting the elastic force of the 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 door body 4. In the 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, and 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 door body 4 can be fixed in the open or closed position.

[0044] Because when the manual drive mechanism 6 is used to control the swing arm 2, it is necessary to disconnect the connection between the swing arm 2 and the hydraulic rod 51 first, so 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 a plug block 533 is inserted in the inside of the through hole 532. The connecting rod 52 is provided with a slot 534 adapted to the plug block 533, and a clamping groove 535 is provided on the side of one end of the plug 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 the top, and a slider 537 compatible with the slot 535 is slidably connected inside the groove 536. The slider 537 is inserted in the slot 535 to limit the insertion block 533, and the insertion block 533 is inserted in 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, so that the connecting rod 52 and the card frame 531 can be separated.

[0045] In order to facilitate the control of the slider 537 to be inserted into the slot 535 and 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 swing of the connecting rod 539 can drive the slider 537 to slide. In this way, the manual mode and the electric mode can be switched by simply rotating the handle 538.

[0046] In order to prevent malicious human rotation of the turning handle 538, a hexagonal groove 5310 is opened at the center position of the top of the connecting rod 539, and an anti-touch cover 5311 for covering the turning handle 538 is installed on the connecting rod 52. A protective plug corresponding to the hexagonal groove 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 accidentally falling off, thereby improving the safety of the equipment.

[0047] When the swing arm 2 is switched to manual mode, in order to prevent the connecting rod 52 from affecting the swing of the swing arm 2, a clamping piece 7 for fixing the connecting rod 52 is provided inside the swing arm 2. The clamping piece 7 includes a connecting column 71 slidably installed in the swing arm 2 up and down, and a pull rod 72 is fixed to the top of the connecting column 71. The upper end of the pull rod 72 passes through the swing arm 2 and is provided with a telescopic spring 73. The two ends of the telescopic spring 73 are respectively fixed to the upper end of the pull rod 72 and the top of the swing arm 2. When the clamping frame 531 and the connecting rod 52 are disconnected, the connecting rod 52 is rotated to the bottom of the swing arm 2, and the pull rod 72 is pulled at the same time to drive the connecting column 71 to slide upward. At this time, the telescopic spring 73 is deformed until the slot 534 on the connecting rod 52 is aligned with the connecting column 71. The connecting column 71 is released, and the connecting column 71 can enter the slot 534 through the elastic force of the telescopic spring 73, so that the connecting rod 52 can be fixed under the swing arm 2 to ensure the smooth swing of the swing arm 2.

[0048] In order to enhance the smoothness of opening and closing of the door body 4, a guide rail 8 is 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 rotatably installed inside the track plate 9, and 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 fluency of opening and closing of the door 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 technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.
