AI Technical Summary
Existing anti-pinch systems for automatic luggage compartments have excessive anti-pinch force or excessive delay due to their large weight and different movement patterns, posing safety hazards. Furthermore, traditional pressure switches and electronic delay anti-pinch systems are not suitable for automatic luggage compartments.
The device employs an anti-pinch airbag system, which combines a cylinder, a pressure sensor, and a solenoid valve. The airbag's deformation senses obstacles and controls the cylinder's movement, achieving a fast and direct anti-pinch function.
With its simple structure and sensitive response, it improves the safety of automatic luggage compartment doors and avoids safety problems caused by excessive anti-pinch force or excessive delay.

TECHNICAL FIELD
[0001] The utility model relates to automatic luggage compartment door anti-pinch technical field, concretely relates to a kind of automatic luggage compartment door air bag anti-pinch device. BACKGROUND
[0002] More and more high-grade luxury coaches discard original manual luggage compartment door and adopt automatic luggage compartment door, and the automatic luggage compartment door generally uses a cylinder as a power source, and opens and closes the luggage compartment door with the opening and closing of the cylinder. Consequently, the automatic luggage compartment door must have a proactive anti-pinch function to ensure the safety of passengers when they are taking out luggage.
[0003] Currently, the anti-pinch function of the automatic luggage compartment door of a coach is borrowed from the anti-pinch function of a passenger door. The existing anti-pinch system of the passenger door mostly uses a pressure switch anti-pinch function, and a pressure sensor is installed at the rear end of the cylinder. When the passenger door is closing and an object is pinched, the movement is blocked, the pressure sensor senses the change in exhaust pressure and sends a signal to the electromagnetic valve, the electromagnetic valve changes direction, the cylinder changes action, the door opens, and the pinched object is released, thereby achieving anti-pinch. In addition, the pressure switch anti-pinch function of the passenger door is also combined with an electronic delay anti-pinch function. When the passenger door is closing and an object is pinched, the movement is blocked, and when the passenger door does not achieve closing within a set time, the electronic delay control box also sends a signal to the electromagnetic valve to change the air path, the cylinder changes action, and anti-pinch is achieved.
[0004] Compared with the vertical translation of the passenger door, the self-weight of the automatic luggage compartment door body and the compartment door outer swing mechanism is large, and the automatic luggage compartment door moves from top to bottom during closing. There are problems such as the anti-pinch force being much larger than that of the passenger door due to the fast movement of the automatic luggage compartment door, or the door not being able to close due to the long delay caused by the stuck movement, and the contact surface of the anti-pinch function has no buffer and is easy to injure people. Therefore, the original pressure switch and electronic delay anti-pinch function are not suitable for the automatic luggage compartment door. SUMMARY
[0005] The utility model aims at overcoming the shortcomings of the prior art, and provides an automatic luggage compartment door air bag anti-pinch device to replace the original automatic luggage compartment door anti-pinch method to solve the hidden dangers of the original anti-pinch method. The automatic luggage compartment door anti-pinch function has the characteristics of high safety, direct action, sensitive response, and simple structure.
[0006] In order to achieve the purpose of the utility model, the technical scheme adopted by the utility model is as follows:
[0007] The utility model discloses an automatic luggage compartment door air bag anti -pinching device, including luggage compartment door, anti -pinch air bag, outer swing mechanism, cylinder device and pressure sensor + electromagnetic valve, the upper portion of luggage compartment door is installed with cabin door electric control lock, the middle part both ends of the luggage compartment door are connected with the one end of outer swing mechanism respectively, the middle part of outer swing mechanism is connected cylinder device, the lower part of luggage compartment door is installed with balance bar, the bottom of luggage compartment door is installed with anti -pinch air bag, the rear portion of cylinder device is installed with pressure sensor + electromagnetic valve, and the anti -pinch air bag and pressure sensor + electromagnetic valve are connected through the trachea.
[0008] The outer swing mechanism is composed of a straight pipe and an L-shaped pipe, the L-shaped pipe is welded at the bottom of both ends of the straight pipe, and the connecting piece welded at the corner of the L-shaped pipe is hinged with the gas spring.
[0009] The trachea is fixed along the outer wall of the luggage compartment door, the outer swing mechanism and the cylinder device.
[0010] The utility model has the advantages of simple and compact structure, direct and agile action, high reliability, direct response when contacting the anti -pinch air bag, rapid and sensitive reaction, and improved safety performance during the operation of the automatic luggage compartment door.

[0016] The utility model is further explained in connection with the drawings and examples:
[0017] Referring to Figs. 1-3 .
[0018] As Figs. 1-2As shown, the utility model discloses an automatic luggage compartment door air bag anti -pinching device, including luggage compartment door 1, anti -pinching air bag 3, outer swing mechanism 4, cylinder device 7 and pressure sensor + electromagnetic valve 9, the upper portion of luggage compartment door 1 is installed with cabin door electric control lock 2, the middle part both ends of luggage compartment door 1 are connected with one end of outer swing mechanism 4 respectively, the middle part of outer swing mechanism 4 is connected cylinder device 7, the lower portion of luggage compartment door 1 is installed with balance bar 6, the bottom of luggage compartment door 1 is installed with anti -pinching air bag 3, the rear portion of cylinder device 7 is installed with pressure sensor + electromagnetic valve 9, and the anti -pinching air bag 3 is connected through air pipe 8 between pressure sensor + electromagnetic valve 9, after giving anti -pinching air bag 3 pressure, make that pressure sensor obtains sensing control electromagnetic valve steering, to control cylinder steering makes luggage compartment door re -lift.
[0019] As Fig. 3 Shown, the outer swing mechanism 4 is composed of straight pipe 401 and L type pipe 402, the both ends bottom of straight pipe 401 is welded with L type pipe 402, and the connecting piece welded at the corner of L type pipe 402 is hinged with gas spring 5.
[0020] The air pipe 8 is fixed along the outer wall of luggage compartment door 1, outer swing mechanism 4 and cylinder device 7, to prevent air pipe from falling off and extruding deformation damage.
[0021] Working principle:
[0022] When the automatic luggage compartment door executes closing action, if the bottom anti -pinching air bag of luggage compartment door meets an obstacle at a certain place in the running track range, the anti -pinching air bag will contact the obstacle and then deform, so that the air pressure in the anti -pinching air bag changes, and the air pressure change transmits the signal to the pressure sensor through the air pipe connected with the pressure sensor, and the pressure sensor receives the signal to make the electromagnetic valve reverse, so as to control the movement of the cylinder device to reverse, and then stop the movement of the luggage compartment door until the luggage compartment door is completely opened, to prevent the passenger or the article from being damaged.
[0023] In addition, when the luggage compartment door is in the locked state, the cabin door electric control lock transmits the locking signal to the pressure sensor, and the pressure sensor does not work, that is, when the air bag is extruded, the pressure sensor also does not work, so that the cabin door closing is stable.
