Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0020] Please refer to Figures 1-3 , the present utility model discloses a two-dimensional code scanner with a supplementary lighting function, which includes a base 1, a scanner main body 2 and a damping rotating shaft 3. The scanner main body 2 is hinged to the base 1 through the damping rotating shaft 3. Through the cooperation between the base 1 and the counterweight plate 13, the circumferential angle adjustment of the scanner can be realized. Through the action of the damping rotating shaft 3, the pitching angle adjustment of the scanner can be realized, which is convenient for scanning and identifying two-dimensional codes at different positions, making the scanner more convenient to use. And when not in use, the scanner main body 2 and the base 1 can be combined together, which is beneficial to protecting the scanning area of the scanner main body 2. An LED light board 11 is embedded in the top of the base 1, and the LED light board 11 is electrically connected to the scanner main body 2 through a flexible cable. A first lens 12 is attached to the top of the base 1. A counterweight plate 13 is movably clamped to the bottom of the base 1, and a human body infrared sensor 25 is built in. When a person holds a two-dimensional code close to the scanner, the sensor outputs a valid signal, and the two-dimensional code scanning module 23 controls the ring-shaped supplementary light 24 and the LED light board 11 to be turned on respectively, which can supplement lighting, enhance the recognition effect, improve the success rate and accuracy of scanning, and thus provide favorable conditions for long-distance code scanning;
[0021] The scanner main body 2 includes a housing 21, a power supply board 22, a two-dimensional code scanning module 23, a ring-shaped supplementary light 24, a human body infrared sensor 25, a cover 26 and a second lens 27. The power supply board 22, the two-dimensional code scanning module 23, the ring-shaped supplementary light 24 and the human body infrared sensor 25 are respectively installed in the housing 21, and the power supply board 22, the ring-shaped supplementary light 24 and the human body infrared sensor 25 are respectively electrically connected to the two-dimensional code scanning module 23. The cover 26 is snap-fitted to the housing 21, and the second lens 27 is embedded in the cover 26.
[0022] Specifically, an ear seat 14 is provided at the rear of the base 1, and one end of the damping rotating shaft 3 is fixed in the ear seat 14.
[0023] In this embodiment, the ear seat 14 is a connecting structure for the installation and fixation between the damping rotating shaft 3 and the base 1. The damping rotating shaft 3 is a shaft that must be used to connect product components and bears both bending moment and torque during rotational work. The principle of the damping rotating shaft 3 is actually to generate frictional force through the extrusion between gaskets. The magnitude of the frictional force is related to the number of installed gaskets and the tightness of the nut tightening.
[0024] Specifically, an ear hole 28 is provided at the bottom of the scanner main body 2, and the other end of the damping rotating shaft 3 is fixed in the ear hole 28.
[0025] In this embodiment, the ear hole 28 is a connecting structure for the installation and fixation between the damping rotating shaft 3 and the scanner main body 2.
[0026] Specifically, a positioning pin 15 is embedded at the bottom of the base 1, and a positioning hole 16 is provided in the middle of the counterweight plate 13, and the counterweight plate 13 is connected to the base 1 through the positioning hole 16 and the positioning pin 15.
[0027] In this embodiment, through the cooperation of the positioning hole 16 and the positioning pin 15, the counterweight plate 13 and the base 1 are assembled together.
[0028] Specifically, a bushing 17 is sleeved on the positioning pin 15, and the bushing 17 is located between the positioning pin 15 and the positioning hole 16.
[0029] In this embodiment, the function of the bushing 17 is to protect the positioning pin 15 from wear, and at the same time increase the frictional force between the positioning pin 15 and the positioning hole 16.
[0030] Specifically, the annular supplementary light 24 is arranged around the lens of the two-dimensional code scanning module 23, and the detection end of the human body infrared sensor 25 exposes outwards from the cover 26.
[0031] In this embodiment, the working principle of the human body infrared sensor 25 is based on infrared radiation induction technology. When a human body enters the sensing area, due to the relatively high body temperature of the human body, infrared rays of different frequencies will be emitted. These infrared rays are received by the sensor and converted into electrical signals. After a series of signal processing, a switching signal is output, thereby controlling the corresponding circuits and devices to achieve corresponding functions.
[0032] During use, a human body infrared sensor 25 is built in. When a person holds a two-dimensional code close to the scanner with their hand, the sensor outputs a valid signal. The two-dimensional code scanning module 23 controls the ring fill light 24 and the LED light board 11 to be turned on respectively, which can supplement lighting, enhance the recognition effect, improve the success rate and accuracy of scanning, thereby providing favorable conditions for long-distance code scanning. Through the cooperation between the base 1 and the counterweight plate 13, the circumferential angle adjustment of the scanner can be achieved. Through the action of the damping rotating shaft 3, the pitching angle adjustment of the scanner can be achieved, facilitating the scanning and recognition of two-dimensional codes at different positions, making the scanner more convenient to use. And when not in use, the scanner main body 2 and the base 1 can be combined together, which is beneficial to protecting the scanning area of the scanner main body 2.
[0033] In summary, for this two-dimensional code scanner with a fill light function, through the cooperation between the base 1 and the counterweight plate 13, the circumferential angle adjustment of the scanner can be achieved. Through the action of the damping rotating shaft 3, the pitching angle adjustment of the scanner can be achieved, facilitating the scanning and recognition of two-dimensional codes at different positions, making the scanner more convenient to use. And when not in use, the scanner main body 2 and the base 1 can be combined together, which is beneficial to protecting the scanning area of the scanner main body 2; a human body infrared sensor 25 is built in. When a person holds a two-dimensional code close to the scanner with their hand, the sensor outputs a valid signal. The two-dimensional code scanning module 23 controls the ring fill light 24 and the LED light board 11 to be turned on respectively, which can supplement lighting, enhance the recognition effect, improve the success rate and accuracy of scanning, thereby providing favorable conditions for long-distance code scanning.
