[0035] It can be understood that, as Figure 5As shown in the figure, in the case where the first connecting part 1 and the second connecting part 2 are in the locked state, the lock rod 14 is locked with the lock block 20, as shown in the figure. Figure 4 As shown in the figure, if it is needed to separate the first connecting part 1 and the second connecting part 2, the electric driving member 12 is driven to drive the lock rod 14 to retract into the seat body 10, so that the lock rod 14 and the lock block 20 are separated, the first connecting part 1 and the second connecting part 2 are in the unlocked state, and then the first connecting part 1 and the second connecting part 2 can be separated.

[0036] Alternatively, after the first connecting part 1 and the second connecting part 2 are separated, there can be at least two cases for the position of the lock rod 14, for example, after the first connecting part 1 and the second connecting part 2 are separated, the lock rod 14 can be kept in the second position, or the lock rod 14 can be switched to the first position.

After the first connecting part 1 and the second connecting part 2 are separated, if the lock rod 14 is in the second position, when it is needed to connect the first connecting part 1 and the second connecting part 2, the electric driving member 12 can be directly controlled to drive the lock rod 14 to move to the first position after the lock block 20 is installed in place, so that the lock rod 14 is locked with the lock block 20.

[0038] Alternatively, the seat body 10 comprises a base 106 and a cover plate 108, and the cover plate 108 covers the base 106 and cooperates with the base 106 to enclose the installation cavity 101.

[0039] As shown in the figure, Figure 1 and Figure 2 According to some embodiments of the present application, the connecting structure of the binding belt 7 further comprises a control assembly 3 electrically connected with the electric driving member 12, for receiving a first operation instruction and a second operation instruction; in the case where the control assembly 3 receives the first operation instruction, the control assembly 3 controls the electric driving member 12 to drive the lock rod 14 to move from the first position to the second position; in the case where the control assembly 3 receives the second operation instruction, the control assembly 3 controls the electric driving member 12 to move from the second position to the first position.

The connecting structure of the strap 7 provided in the application can realize the quick disassembly of the strap 7 without manual operation of mechanical parts, and the convenience and operation efficiency are improved. At the same time, the physical force is replaced by the electric signal instruction, which effectively avoids the accidental loosening caused by accidental touch or vibration, and significantly enhances the reliability and safety of the locking state.

[0041] Optionally, any one of the first operation instruction and the second operation instruction can be an instruction input by the user, or an instruction output by other electronic devices according to the detection result.

[0042] As shown in Figure 1 and Figure 2 According to some embodiments of the application, the electric driving part 12 comprises an electromagnet 120 fixedly arranged in the mounting cavity 101, the electromagnet 120 is located on the side of the locking rod 14 away from the through hole 100; an elastic part 122, one end of the elastic part 122 is fixed, and the other end of the elastic part 122 is connected with the locking rod 14 to drive the locking rod 14 to reset in the case that the electromagnet 120 is in the power-off state; the locking rod 14 comprises a magnetic attraction structure, so that the locking rod 14 is driven to move between the first position and the second position by controlling the electromagnet 120 to switch between the power-on state and the power-off state.

[0043] In this embodiment, the electric driving part 12 comprises an electromagnet 120 and an elastic part 122, and the locking rod 14 comprises a magnetic attraction structure. When the electromagnet 120 is in the power-on state, the electromagnet 120 generates a magnetic force and attracts the locking rod 14, so that the locking rod 14 moves; when the electromagnet 120 is in the power-off state, the electromagnet 120 loses the attraction force to the locking rod 14, and then the locking rod 14 resets under the action of the elastic part 122. That is, in the embodiments provided in the application, the electromagnet 120 is switched between the power-off state and the power-on state, so that the locking rod 14 moves between the first position and the second position.

[0044] Optionally, when the electromagnet 120 is in the power-off state, the elastic part 122 can drive the locking rod 14 to move from the first position to the second position, and when the electromagnet 120 is in the power-on state, the electromagnet 120 drives the locking rod 14 to move from the second position to the first position; or, when the electromagnet 120 is in the power-off state, the elastic part 122 can drive the locking rod 14 to move from the second position to the first position, and when the electromagnet 120 is in the power-on state, the electromagnet 120 drives the locking rod 14 to move from the first position to the second position.

[0047] In this embodiment, when the electromagnet 120 is in the energized state, the electromagnet 120 generates a magnetic force and attracts the lock rod 14, so that the lock rod 14 overcomes the elastic force of the elastic member 122 and moves to the second position, so that the lock rod 14 is retracted into the mounting cavity 101, and at this time the elastic member 122 is in the energy storage deformed state; when the electromagnet 120 is in the de-energized state, the magnetic force of the electromagnet 120 disappears, the elastic member 122 quickly releases the stored elastic potential energy, drives the lock rod 14 to move to the first position, and at least part of the lock rod 14 extends outside the seat body 10 through the through hole 100. The connection structure of the binding belt 7 proposed in the present application realizes the extension and retraction actions of the lock rod 14 under the cooperation of the electromagnet 120 and the elastic member 122, which not only guarantees the efficiency and accuracy of the locking and unlocking processes, but also simplifies the structure, and does not need manual intervention, thereby improving the convenience and operation efficiency.

[0050] Optionally, along the moving direction of the locking rod 14, the elastic element 122 is located on the side of the mounting base 140 facing the through hole 100, and the elastic element 122 is in a stretched state when the locking rod 14 is retracted into the base 10; or along the moving direction of the locking rod 14, the elastic element 122 is located on the side of the mounting base 140 away from the locking rod 14, and the elastic element 122 is in a compressed state when the locking rod 14 is retracted into the base 10.

[0051] In this embodiment, the elastic element 122 can be disposed on the side of the mounting base 140 facing the through hole 100, so that when the locking rod 14 retracts into the base 10, the elastic element 122 is stretched and stores energy; the elastic element 122 can also be disposed on the side of the mounting base 140 away from the through hole 100, so that when the locking rod 14 retracts into the base 10, the elastic element 122 is compressed and stores energy. Whether the elastic element 122 is stretched or compressed, it ensures a reliable driving force when the electromagnet 120 is de-energized, allowing the locking rod 14 to extend and lock the first connecting part 1 and the second connecting part 2.

[0052] Optionally, the elastic element 122 may include a spring, an elastic rubber element, etc.

At least one end of the elastic element 122 is provided with a snap-fit ​​structure 124. Through the limiting cooperation between the snap-fit ​​structure 124 and the slot structure 102, the position of the elastic element 122 is fixed, thereby ensuring the reliability of the deformation of the elastic element 122 during the movement of the locking rod 14, so as to ensure the reliability of the reset of the locking rod 14.

In addition, the motor drive is easy to realize stroke control and position feedback, which is beneficial to realize accurate judgment of the connection state.

Therefore, when the first connecting part 1 and the second connecting part 2 are connected, the Hall element 40 detects that the magnetic field of the magnetic member 50 is stable, which indicates that the first connecting part 1 and the second connecting part 2 are installed in place, i.e., the second connecting part 2 is in the locked position relative to the first connecting part 1, at this time the Hall element 40 feeds back an electrical signal to the control assembly 3, so that the control assembly 3 controls the electric drive member 12 to release the lock rod 14, for example, the control assembly 3 controls the electromagnet 120 to be powered off, or controls the motor to drive the lock rod 14 to extend out of the through hole 100.
