Detailed implementation manner

[0020] The following describes the detailed implementation manner of the embodiment of the present invention with reference to the accompanying drawings.

[0021] Refer to Figure 1 , a mechanism for remotely controlling the opening and closing of a hatch, including a vehicle controller 10, a vehicle-mounted communication unit 11, an automatic door mechanism 20, a vibration sensor 40, an electric control lock 51, an anti-theft camera 61, an induction camera 62, and a sound and light alarm 70. The vehicle controller 10 is electrically connected to the vehicle-mounted communication unit 11, the automatic door mechanism 20, the vibration sensor 40, the electric control lock 51, the anti-theft camera 61, the induction camera 62, and the sound and light alarm 70 respectively.

[0022] Refer to Figure 1 , the automatic door mechanism 20 includes an upper guide rail 21 and a lower guide rail 22 respectively fixedly installed on the upper and lower sides of the vehicle body door frame, a door body 23 disposed between the upper guide rail 21 and the lower guide rail 22 and movable along the guide rail direction, and a power mechanism 30 for driving the movement of the door body 23. In this embodiment, upper pulley assemblies 24 and lower pulley assemblies 25 are respectively fixedly provided on the upper and lower sides of the door body 23, and the door body 23 is connected to the upper guide rail 21 and the lower guide rail 22 through the upper pulley assemblies 24 and the lower pulley assemblies 25 respectively. The power mechanism 30 includes a stepper motor 31 installed on the vehicle body, a gearbox 32 connected to the output shaft of the stepper motor 31, a gear 33 fixedly connected to the output shaft of the gearbox 32, and a parallel rack 34 meshing with the gear 33. The parallel rack 34 is fixedly installed on the door body 23 and is parallel to the upper guide rail 21.

[0023] Refer to Figure 1 , when the door of the present invention is opened or closed, the stepper motor 31 receives a fixed number of pulse signals from the vehicle controller 10, rotates forward and backward a certain number of turns, and converts the rotational speed into the rotational speed of the gear 33 through the gearbox 32. By means of the meshing of the gear 33 and the parallel rack 34, the parallel rack 34 is pulled, thereby pulling the movement of the door panel. During this movement process, the upper and lower pulley assemblies (24, 25) and the upper and lower guide rails (21, 22) can play a role in supporting the door panel and guiding the movement. At the same time, in order to ensure smooth movement, lubricating grease can be applied to the contact surfaces between the upper and lower pulley assemblies (24, 25) and the upper and lower guide rails (21, 22).

[0024] The vibration sensor 40 can be selected as one or more vibration sensors 40 according to the door size or layout requirements. The vibration sensor 40 is installed on the door body 23 of the vehicle door and is used to sense the vibration amplitude of the door body 23 of the vehicle door.

[0025] Refer to Figure 1 , the electric control lock 51 is used to lock the door body 23 of the vehicle door. The electric control lock 51 can be arranged on the vehicle body door frame or the door body 23 of the vehicle door. In this embodiment, the electric control lock 51 is preferably arranged at the bottom of the door body 23 of the vehicle door. The locking post of the electric control lock 51 faces the lower side of the vehicle body door frame, and a locking groove 52 matching with the locking post of the electric control lock 51 is correspondingly arranged on the lower side of the vehicle body door frame. Due to the special application of the electric control lock 51 of the present utility model (the special application of the electric control lock 51 will be elaborated later), the structure of its locking groove 52 can be preferably a strip-shaped locking groove 52, and the strip-shaped locking groove 52 can ensure that even if the door body 23 of the vehicle door has a small displacement, the locking post of the electric control lock 51 can still be inserted into the strip-shaped locking groove 52.

[0026] There are two cameras inside and outside the vehicle door of the present utility model, namely an anti-theft camera 61 and an induction camera 62. The anti-theft camera 61 is arranged on the side of the door body 23 of the vehicle door facing the outside of the vehicle, or is arranged on the vehicle body and shoots towards the vehicle door. The induction camera 62 is arranged on the side of the door body 23 of the vehicle door facing the inside of the vehicle, or is arranged inside the vehicle body, and is used to sense whether there are foreign objects, people or animals within the range of the vehicle door opening and closing. If the induction camera 62 senses that there are foreign objects, people or animals within the range of the vehicle door opening and closing, the vehicle door switch will be suspended through the vehicle controller 10. If there is no induction, the vehicle door will be switched normally. The application of the induction camera 62 of the present utility model belongs to the prior art in the field of the automatic vehicle door anti-pinch function, and its working principle will not be elaborated here.

[0027] The sound and light alarm bell 70 is used to emit sound and light alarms. The sound and light alarm bell 70 can be arranged anywhere on the vehicle body, and the vehicle-mounted communication unit 11 is used to dial the corresponding alarm phone number after the sound and light alarm is issued.

[0028] Refer to Figure 1 and Figure 2 , the specific working process of the vibration anti-theft alarm of the present utility model is as follows:

[0029] The vibration sensor 40 senses whether there is vibration on the vehicle door body 23. When there is vibration, it sends a signal to the vehicle controller 10, and the vehicle controller 10 judges according to the current state of the vehicle. If the vehicle is currently in a driving state, it is ignored. If the vehicle is currently in a parked state and the door is closed, it is determined that there is an external force trying to violently open the door in an abnormal way. The vehicle controller 10 sends an instruction to the vehicle's audible and visual alarm 70, and the audible and visual alarm 70 emits an audible and visual alarm. At the same time, a signal is also sent to the vehicle-mounted communication unit 11 to dial the corresponding alarm phone. At the same time, the anti-theft camera 61 takes pictures outside the vehicle for subsequent investigation. At the same time, an instruction is sent to the electric control lock 51, and the lock post of the electric control lock 51 extends and inserts into the locking groove 52 to play a dual locking function. Through the above linkages, the valuable equipment inside the vehicle is ensured.

[0030] As a supplement, the electric control lock 51 of the present invention belongs to a trigger-type second anti-theft lock structure, and its activation timing is when the door is violently opened. Therefore, the structure of the locking groove 52 of the present invention can be preferably a strip-shaped locking groove 52. The strip-shaped locking groove 52 can ensure that even after the vehicle door body 23 has a small displacement, the lock post of the electric control lock 51 can still insert into the strip-shaped locking groove 52 to complete the locking and limiting function.

[0031] The above is only the specific implementation manner of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantive modification of the present invention using this concept shall fall within the scope of infringement of the protection of the present invention.
