[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1 The utility model provides a technical solution for a wing-opening hydraulic system for a vehicle door: a wing-opening hydraulic system for a vehicle door, comprising a main body 1, the interior of the main body 1 is connected to a support rod 2 through a piston, two groups of locking assemblies 3 are symmetrically arranged on the outside of the support rod 2, and the two groups of locking assemblies 3 are used to lock the support rod 2 when the pressure in the hydraulic rod is abnormal, a mounting assembly 4 is commonly connected between the main body 1 and the two groups of locking assemblies 3, two groups of pressure detection assemblies 5 are installed on the outside of the main body 1, a first mounting head 6 is installed on the free end of the main body 1, a second mounting head 7 is installed on the free end of the support rod 2, and inner movable heads 8 are arranged inside the first mounting head 6 and the second mounting head 7.

[0022] It should be noted that by fixing the mounting assembly 4 to the outside of one end of the main body 1, the two sets of locking assemblies 3 are located outside the support rod 2, and then the pressure detection assembly 5 detects the pressure value inside the main body in real time. When the value exceeds the set value, an alarm and data transmission are performed through the external PC terminal and the two sets of locking assemblies 3, so that the two sets of locking assemblies 3 magnetically lock the support rod 2 to prevent the hydraulic rod from failing to provide support, causing the door to fall directly, which may cause certain injuries to the user, and when the door needs to be closed, the two sets of locking assemblies 3 are unlocked on the support rod 2 through the external PC terminal, so that the support rod 2 can enter the interior of the main body 1, thereby closing the door.

[0023] See also Figure 2-4 The locking assembly 3 includes an arc-shaped plate 31, and two groups of grooves 32 are provided on the inner arc surface of the arc-shaped plate 31. The inner side surface of each group of grooves 32 is connected to a telescopic rod 33 and a spring 34. The free ends of the telescopic rod 33 and the spring 34 are commonly connected to a mounting plate 35. An electromagnet 36 is installed on the side of each group of mounting plates 35. A chamber 37 is provided inside the arc-shaped plate 31, and a controller 38 and a signal receiving module 39 are installed inside the chamber 37. There is a gap between the inner arc surface of the arc-shaped plate 31 and the outer surface of the support rod 2. The free end side surface of each group of electromagnets 36 is an arc-shaped structure and is adapted to the outer surface structure of the support rod 2.

[0024] It should be noted that the controller 38 is used to control the electromagnet 36 to work and shut down, and the signal receiving module 39 is used to receive the detection data of the two groups of pressure detection components 5 and the instructions sent by the external PC;

[0025] When the electromagnet 36 is started, the electromagnet 36 drives the mounting plate 35 to move toward the support rod 2 until the inner arc surface of the electromagnet 36 and the outer surface of the support rod 2 are in contact with each other and magnetically attracted. At this time, the mounting plate 35 is located inside the groove 32 and stretches the spring 34, so that the multiple groups of electromagnets 36 lock the position of the support rod 2.

[0026] When the electromagnet 36 is closed, the spring 34 contracts and stretches the mounting plate 35 and the electromagnet 36 to move outward, so that the electromagnet 36 is separated from the surface of the support rod 2, thereby releasing the locking of the support rod 2 by the multiple groups of electromagnets 36.

[0027] See also Figure 5The mounting assembly 4 includes a first half ring 41 and a second half ring 42. The outer surface of one end of the first half ring 41 is symmetrically connected with two groups of first protrusions 43, and the outer surface of one end of the second half ring 42 is symmetrically connected with two groups of second protrusions 44. The interior of each group of first protrusions 43 is rotatably connected with a rotating seat 45, and the side of each group of rotating seats 45 is connected with bolts 46. The side of each group of second protrusions 44 is provided with a U-shaped groove 47, and each group of bolts 46 passes through each group of U-shaped grooves 47. The free end of each group of bolts 46 is threadedly connected with a butterfly nut 48. The inner surface of one end of the first half ring 41 and the second half ring 42 is fixedly connected to the outer surface of the two groups of arc plates 31, and the other end of the first half ring 41 and the second half ring 42 is located outside the body 1.

[0028] It should be noted that, by closing the first half ring 41 and the second half ring 42 on the outside of the main body 1, and then flipping the bolt 46 through the rotating seat 45, so that the bolt 46 passes through the U-shaped groove 47, thereby tightening the butterfly nut 48, the first half ring 41 and the second half ring 42 are fixed to the outside of the main body 1, conversely, the butterfly nut 48 is loosened, the bolt 46 is flipped by the rotating seat 45, so that the bolt 46 moves out of the U-shaped groove 47, and the first half ring 41 and the second half ring 42 can be removed. This structure is convenient for fixing the locking assembly 3 and the hydraulic cylinder, and when the hydraulic cylinder is inspected or replaced, it is convenient to disassemble the installation assembly 4 and the two sets of locking assemblies 3, and reuse the installation assembly 4 and the two sets of locking assemblies 3.

[0029] Working principle of the utility model: when in use, the first half ring 41 and the second half ring 42 are closed outside the body 1, and then the bolt 46 is turned over by the rotating seat 45, so that the bolt 46 passes through the U-shaped groove 47, and the butterfly nut 48 is tightened, and the first half ring 41 and the second half ring 42 are fixed outside the body 1, so that the two sets of locking components 3 are located outside the support rod 2;

[0030] Then, the two groups of pressure detection components 5 detect the pressure value inside the body in real time. When the value exceeds the set value, an alarm is issued and data is transmitted through the external PC terminal and the two groups of locking components 3. When the electromagnet 36 is started, the electromagnet 36 drives the mounting plate 35 to move toward the support rod 2 until the inner arc surface of the electromagnet 36 and the outer surface of the support rod 2 are in magnetic contact. At this time, the mounting plate 35 is located inside the groove 32 and the spring 34 is stretched. Then, the multiple groups of electromagnets 36 lock the position of the support rod 2 to prevent the hydraulic rod from failing to support the door, causing it to fall directly, which may cause certain injuries to the user.

[0031] When the door needs to be closed, the two sets of locking components 3 are unlocked on the support rod 2 through the external PC end. When the electromagnet 36 is closed, the spring 34 contracts and stretches the mounting plate 35 and the electromagnet 36 to move outward, so that the electromagnet 36 and the surface of the support rod 2 are separated, and the locking of the support rod 2 by the multiple sets of electromagnets 36 is released, so that the support rod 2 can enter the interior of the body 1, thereby closing the door;

[0032] When the hydraulic cylinder is inspected or replaced, the butterfly nut 48 is loosened, and the bolt 46 is turned over by the rotating seat 45 so that the bolt 46 moves out of the U-shaped groove 47, and the first half ring 41 and the second half ring 42 and the two sets of locking components 3 can be removed.
