[0019] Example 1

[0020] like Figures 2-3 The battery compartment door axis sensing structure shown in the figure for a battery exchange cabinet includes a battery compartment 1, a compartment door 2, a magnet 21, a door axis detection switch 3, a detection terminal 31, a sensing block 302, a first wiring harness 32, a counterweight 33, a second wiring harness 34, a magnetic sheet 35, a storage box 4, a second seam 41, a limiting plate 5, a first seam 51, a safety rope 6 and a fixing screw 7.

[0021] Among them, such as Figure 1 As shown, the door shaft detection switch 3 is a U-shaped structure, and the detection terminal 31 is located in the middle of the door shaft detection switch 3 and slides left and right. When the sensing block 302 in the middle of the detection terminal 31 is facing the door shaft detection switch 3, the door shaft detection switch 3 detects a signal, otherwise it is detected as no signal. The signal and no signal correspond to the door open state and the door closed state respectively.

[0022] Specifically, the detection terminal 31 is connected with the suspended counterweight 33 through the first wire harness 32 at one end, and is connected with the magnetic sheet 35 through the second wire harness 34 at the other end, and the magnetic sheet 35 is matched with the magnet 21 installed on the door 2. In this way, when the door 2 is closed, the magnet 21 attracts the magnetic sheet 35, thereby pulling the detection terminal 31 to move to the left, so that the inductive block 302 is opposite to the door shaft detection switch 3, and the detection result is a signal, at this time, it is judged that the door has been closed. When the door 2 is opened, the magnetic sheet 35 loses the magnetic force adsorption, at this time, the counterweight 33 pulls the detection terminal 31 through the first wire harness 32, so that the detection terminal 31 moves to the right, and the detection result of the door shaft detection switch 3 is no signal, that is, it is judged that the door has been opened. Wherein, the door shaft detection switch 3 and the inductive block 302 can be corresponding inductive structures such as magnetic inductor and magnetic block.

[0023] Further, the magnetic sheet 35 is in the storage box 4, the storage box 4 is formed with the second wire seam 41 for the second wire harness 34 to pass through; the battery compartment 1 is fixed with the limiting plate 5, the limiting plate 5 is formed with the serpentine first wire seam 51, and the first wire harness 32 passes through the first wire seam 51 to connect the counterweight 33, so that the movement range of the magnetic sheet 35 is limited through the storage box 4, and the first wire harness 32 is effectively prevented from being separated from the first wire seam 51 through the serpentine first wire seam 51. In order to prevent the counterweight 33 from falling into the cabin after the first wire harness 32 is broken, the fixed screw 7 is fixed in the battery compartment 1, and the fixed screw 7 is connected with the counterweight 33 through the safety rope 6.

[0024] Although the embodiments of the utility model have been disclosed as above, it is not limited to the application listed in the specification and the embodiments, it can be fully applied to various fields suitable for the utility model, and for those skilled in the art, other modifications can be easily realized, therefore, the utility model is not limited to specific details and the drawings shown and described herein, without departing from the general concept defined by the claims and equivalent scope.
