Description

Technical Field

[0001] This utility model relates to the field of handheld computer technology, specifically to a handheld mobile computer with barcode scanning and heating functions. Background Technology

[0002] A handheld mobile computer, also known as a handheld terminal, is a portable handheld electronic device, commonly referred to as a barcode scanner, data collector, etc. It can replace traditional laptops to automate and manage daily work and personal functions, while allowing users to easily manage their information even when they are out and about.

[0003] When existing handheld devices are used, if they suddenly move from a low-temperature environment to a high-temperature environment, the surface temperature of the handheld device remains relatively low due to the increase in ambient temperature. Water vapor in the surrounding air will adhere to the surface of the protective film when it cools down, causing the camera to be unable to accurately read barcode information, thereby reducing the scanning efficiency of the device. To address this issue, a handheld mobile computer with barcode scanning and heating functions is proposed. Utility Model Content

[0004] The purpose of this invention is to solve the problem that water vapor in the air adheres to the surface of the protective sheet when it cools down, causing the camera to be unable to accurately read barcode information, thereby reducing the scanning efficiency of the device. This invention provides a handheld mobile computer with barcode scanning and heating functions.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0006] A handheld mobile computer with barcode scanning and heating functions includes:

[0007] A fixed frame, with a battery located on its outer side;

[0008] A heating mechanism, located inside a fixed frame, is used to evaporate condensate. The heating mechanism includes a first heating element and a second heating element. The first heating element is located inside the fixed frame and is used to heat the display. The second heating element is located inside the fixed frame and is used to heat the camera. The first heating element works in conjunction with the second heating element to ensure clarity during use.

[0009] Furthermore, the first heating element includes a display screen, which is disposed inside the fixed frame. Protective sheets and heating elements are respectively provided on both sides of the display screen. A support frame is provided on the outside of the heating element, and the support frame is connected to the fixed frame.

[0010] Furthermore, the second heating element includes a fixing frame, which is disposed inside a fixing frame. A heating pad, a protective sheet, and a limiting frame are sequentially arranged on one side of the fixing frame, and the limiting frame is connected to the fixing frame. A wire and a connecting block are sequentially arranged on the outside of the heating pad.

[0011] Furthermore, both the protective sheet and the protective plate are made of transparent glass.

[0012] Furthermore, an input component is also provided on the outside of the fixed frame.

[0013] The beneficial effects of this utility model are as follows:

[0014] This invention, through the setting of a second heating element, achieves heating of the protective sheet during use by setting up a fixing frame, heating pad, wire, and connecting block. This prevents water vapor in the air from adhering to the surface of the protective sheet when it cools down, thus avoiding the camera's inability to accurately read barcode information and improving the scanning efficiency of the device.

[0026] like Figures 1 to 5 As shown, a handheld mobile computer with barcode scanning and heating functions includes: a fixed frame 1, with a battery 101 disposed on the outside of the fixed frame 1; and a heating mechanism disposed inside the fixed frame 1 for evaporating condensate. The heating mechanism includes a first heating element 3 and a second heating element 4. The first heating element 3 is disposed inside the fixed frame 1 for heating the display, and the second heating element 4 is disposed inside the fixed frame 1 for heating the camera. The first heating element 3 and the second heating element 4 work together to ensure clarity during use. Specifically, the fixed frame 1 also contains a camera for scanning objects and a display module for displaying the scanned information. During use, the first heating element 3 and the second heating element 4 work together to evaporate condensate on the outside of the camera and the display module, ensuring clarity of the camera and the display module during use.

[0027] like Figures 1 to 5As shown, the first heating element 3 includes a display screen 302, which is disposed inside the fixed frame 1. A protective sheet 301 and a heating element 303 are respectively provided on both sides of the display screen 302. A support frame 304 is provided on the outer side of the heating element 303, and the support frame 304 is connected to the fixed frame 1. Specifically, during use, the protective sheet 301 protects the display screen 302 to ensure its stability during use, while the support frame 304 provides support to the display screen 302 to prevent deformation during use. The heating element 303 is connected to the battery 101 via a connecting wire, thereby heating the display screen 302 and the protective sheet 301 during use, preventing condensation from forming on the protective sheet 301 and the display screen 302 when used under large temperature differences. The heating element 303 contains a heating resistance wire.

[0028] like Figures 1 to 5 As shown, the second heating element 4 includes a fixing frame 401, which is disposed inside the fixing frame 1.

A wire 403 and a connecting block 404 are sequentially arranged on the outside of the heating pad 402. Specifically, during use, the protective sheet 405 protects the camera to ensure the clarity of the camera surface. The limiting frame 406, in conjunction with the fixing frame 401, limits the position of the protective sheet 405 to ensure the stability of the protective sheet 405 during use. The heating pad 402 contains a heating resistance wire, which heats the protective sheet 405 during use. The resistance wire inside the heating pad 402 is connected by the wire 403.

[0029] like Figures 1 to 5 As shown, both the protective sheet 405 and the protective sheet 301 are made of transparent glass. Specifically, the glass protective sheet 405 and the protective sheet 301 can protect the camera and the display screen 302 during use, ensuring that the camera and the display screen 302 can be used stably.
