The battery module 700 is provided with the interface that charges, and the interface that charges locates interface 113 department, and the charging wire can be through interface 113 and insert the interface that charges to charge for battery module 700.

Referring to fig. 5, further, the second half-shell 120 is provided with an avoiding hole 122, and the avoiding hole 122 and the operation hole 121 are located on two opposite sides of the second half-shell 120.

Optionally, the handle 130 is rotatably connected to the second half-shell 120, and the handle 130 can be rotated to a position folded on the outer wall of the second half-shell 120, so that the overall volume is small. When the electronic scale is used for weighing, the handle 130 is rotated to be opened relative to the second half-shell 120.

In this embodiment, the tape 410 optionally includes a tape 410 body, a mandrel disposed in the receiving cavity 140 and rotatably connected to the housing 100, and a spring, for example, the mandrel has one end rotatably connected to the first half-shell 110 and the other end rotatably connected to the second half-shell 120. One end of the tape 410 body is connected with the clockwork spring, the clockwork spring is wound outside the mandrel, and the tape 410 body is wound outside the mandrel and covers the clockwork spring. In the process of pulling the tape measure 410 body, the mandrel is driven to rotate, the tape measure 410 body is gradually unwound and extends out of the operation hole 121, and the length of an article is measured.

It should be understood that, in order to use the tape measure 410 body, the slider of the tape measure 410 body is located outside the operation hole 121 and abuts against the outer wall of the second half-shell 120, and the slider does not retract into the accommodating cavity 140.

In addition, in order to prevent the main body of the measuring tape 410 from being pulled by the spring to automatically retract into the accommodating cavity 140 during measurement, the length measuring module 400 further comprises a self-locking mechanism, the main body of the measuring tape 410 is connected with the housing 100 through the self-locking mechanism, the self-locking mechanism has a locking state and an unlocking state which are mutually switched, and when the main body of the measuring tape 410 is in the locking state, the rewinding of the main body of the measuring tape 410 is locked, namely after the main body of the measuring tape 410 is elongated, even if external force is removed, the main body of the measuring tape 410 cannot retract under the action of the spring, and the safety is high. In the unlocked state, tape 410 can be rewound. The self-locking mechanism can be adjusted through a key to switch between a locking state and an unlocking state. For example, when a button is pressed, the self-locking mechanism is switched from the locked state to the unlocked state. After the key is released, the self-locking mechanism is always in a locking state.

Optionally, the self-locking mechanism is configured as a damping structure or a ratchet structure. Taking the self-locking mechanism as an example of a damping structure, the damping structure includes a first damping fin and a second damping fin, the first damping fin and the second damping fin are both disposed in the hole wall of the operation hole 121 and are disposed at intervals, and the main body of the tape measure 410 can extend out from between the first damping fin and the second damping fin. When the self-locking mechanism is in a locking state, the distance between the first damping sheet and the second damping sheet is D1, at the moment, after the tape measure 410 main body is pulled out, the restoring force of the spring is smaller than the damping force, and the tape measure 410 main body cannot automatically retract. When the tape measure 410 body needs to be retracted, the distance between the first damping sheet and the second damping sheet is adjusted to D2, D2 is larger than D1, and therefore the damping force is reduced, and the restoring force of the spring pulls the tape measure 410 body to reset.

It should be understood that the first damping fin and the second damping fin may be both cylindrical plastic sleeves, or the first damping fin and the second damping fin may be a combined structure of a plastic sleeve and a hardware sleeve.

Furthermore, the surface of the main body of the measuring tape 410 is provided with a fluorescent layer, so that accurate measurement can be performed in a dark environment, and the environmental adaptability is strong. Moreover, the scale marks on the main body of the tape measure 410 can be illuminated by the fluorescent layer, and the length measurement can be carried out in a dark environment when the length measurement sensor 420 fails, so that the application range is wide.

It should be understood that the length measuring sensor 420 may be configured as a capacitive sensor, which is activated by pulling the tape 410 body, and the length of the tape 410 body is measured and displayed according to the change of the outer diameter and the number of turns of the tape 410 body wound around the mandrel.

Obviously, when regular objects such as a square body are measured, the volume of the measured object can be calculated by measuring three data of length, width and height, and the measuring device is flexible to use.

In this embodiment, optionally, the weighing module 300 includes a hook 310 and a load cell 320, the load cell 320 is connected to the housing 100, and the load cell 320 is communicatively connected to the circuit board 200; the hook 310 is connected with the load cell 320, and the hook 310 is used for hanging an object to be measured.

Further, the hook 310 is in folding fit with the second half-shell 120, and the hook 310 can be folded onto the second half-shell 120 when not in use, so that the overall volume is reduced.

In this embodiment, optionally, the multifunctional electronic scale further comprises a broadcast module, the broadcast module is connected with the casing 100, the broadcast module is in communication connection with the circuit board 200, and the broadcast module is used for broadcasting data information.

It should be understood that the broadcast module can be a loudspeaker, and after once measuring, the broadcast module reports out measured data automatically, also reminds the operating personnel that the current operation is accomplished, and the operating personnel can carry out next measurement operation, improves the operating efficiency.
