Referring to fig. 1 to fig. 6, in an embodiment, the wearable scanner 10 includes: a wearing portion (not shown), a scanner body 11, and a control assembly 20. The wearing part is used for wearing the wearable scanner on a human body. The scanner body 11 is provided with a processing unit (not shown), a scanning unit 110, and a display unit 120. Specifically, the scanning unit 110 is used for scanning a barcode and for transmitting information of the barcode to the processing unit; the scanning unit 110 may include a camera for acquiring barcode information. The display unit 120 is connected to the processing unit and is used for user interaction, displaying information of the barcode transmitted by the processing unit, or displaying other related information.

Specifically, the user may perform corresponding processing on the barcode information through the content presented by the display unit 120, such as: the information of the barcode is uploaded to other terminals, or the kind and specification of the goods are checked through the information of the barcode, and the like, and the display unit 120 may also be touched to implement related operations.

Further, the scanner body 11 is further provided with a connection unit 130, and the control assembly 20 is detachably connected to the connection unit 130 of the scanner body 11. The control component 20 is connected to the processing unit through the connection unit 130, the control component 20 is used for generating an input signal corresponding to a user operation, and the processing unit receives the input signal and controls the scanning unit 110 to perform a corresponding operation. The corresponding operation may be, for example, turning on a scanning function of the scanning unit 110, and the scanning unit 110 may capture image information such as a barcode.

It should be understood that the bar codes in the various embodiments include, but are not limited to, one-dimensional bar codes and two-dimensional bar codes.

As shown in FIG. 3, in one embodiment, the connection unit 130 includes a first conductive end 131 and a second conductive end 132, and both the first conductive end 131 and the second conductive end 132 are electrically connected to the processing unit. After the connection unit 130 is detachably connected to the control assembly 20, the first conductive terminal 131 and the second conductive terminal 132 are in contact with the control assembly 20, that is, the first conductive terminal 131 and the second conductive terminal 132 are kept in an open state in a normal non-operating state.

In an implementation scenario, when the control component 20 is not triggered, the first conductive terminal 131 and the second conductive terminal 132 are in an open state, and after the control component 20 is triggered, the first conductive terminal 131 and the second conductive terminal 132 are connected to implement scanning.

In another implementation scenario, when the scanning unit 110 senses a barcode, the barcode can be scanned without the control component.

In one embodiment, the first conductive terminal 131 and the second conductive terminal 132 are turned on after the control assembly 20 responds to a user operation (e.g., touching or pressing) to generate the input signal. Based on this, the processing unit receives the input signal and outputs a control signal, and then controls the scanning unit 110 to perform a corresponding operation by generating the control signal to the scanning unit 110.

Specifically, the first conductive terminal 131 and the second conductive terminal 132 are respectively connected to two pins of the processing unit, and when the first conductive terminal 131 and the second conductive terminal 132 are conducted, the two pins of the processing unit are shorted to generate the input signal.

second faces

2121 and 2122, and insulative frame 212 is further provided with a pass-through region 2123 that passes through first and

second faces

2121 and 2122. The key film 211 is attached to the first surface 2121; the keys 213 are provided on a side of the key film 211 facing the first face 2121, and the keys 213 are provided to correspond to the through regions 2123. The key film 211 is made of an insulating material.

Wherein, buffer cotton or a buffer pad can be clamped between the key membrane 211 and the key 213 to reduce the contact pressure amplitude and force.

The key film 211 presses the key 213 through the through region 2123 under a force, and the key 213 is pressed and deformed to be conducted and to be in contact with the first conductive terminal 131 and the second conductive terminal 132, so as to make the first conductive terminal 131 and the second conductive terminal 132 conducted, and the processing unit controls the scanning unit 110 to perform a corresponding operation.

As shown in fig. 4, the insulating frame 212 is illustrated as a rectangular shape penetrating through the middle, and the insulating frame 212 has a frame structure in a shape of a letter "return" as a whole. The scanner body 11 has a groove (not labeled) corresponding to the insulating frame 212, the groove is used for accommodating the connection unit 130, and the groove is further used for the insulating frame 212 of the first control assembly 210 to be embedded. Therefore, after the first control element 210 is connected to the connection unit 130, the first control element 210 is attached to the groove wall of the groove, and the first control element 210 and the scanner body 11 form a relatively flat surface together, so that the connection stability between the first control element 210 and the scanner body 11 can be improved.

The flexible lead 222 is used to make the control portion 223 able to be placed at a position outside the wearable scanner 10 within the line length range of the flexible lead 222 after the wearable scanner 10 is worn on the human body. Therefore, the wearable scanner 10 does not need to touch and press a switch (e.g., the first control component 210) connected to the scanner body 11 intentionally, so that the user can scan and obtain the information of the barcode conveniently.

The control part 223 is provided with a touch switch 2231, and the touch switch 2231 is used for being touched and pressed by a user; after the touch switch 2231 is touched, the first conductive terminal 131 and the second conductive terminal 132 are conducted through the flexible conductive line 222 and the connecting portion 221, so as to control the scan unit 110 to start scanning. It should be understood that the control portion 223 can be distanced from the scanner body 11 by the flexible wire 222; accordingly, after the wearable scanner 10 is worn, equivalently, the control portion 223 can be away from the worn part by a certain distance by using the flexible lead 222, so that the user can conveniently and conveniently start scanning.

In some implementations, after the user wears the wearable scanner 10, the user can operate the wearable scanner 10 with one hand via the second control component 220.
