Detailed Description

For a better understanding of the objects, structure, features, and functions of the present application, reference should be made to the drawings and detailed description that follow.

The application provides a handheld terminal 1 with improved water and dust resistance.

As shown in fig. 1, the handheld terminal 1 according to the first embodiment of the present disclosure includes a housing 11, wherein a collecting window 13 is disposed on a front end surface of the housing 11, and the collecting window 13 is covered by a transparent sheet 14. The side of shell 11 is equipped with an interface 12, interface 12 can supply to charge or transmit data or install memory card etc. interface 12 with the inside clearance of handheld terminal 1 has reached higher waterproof dustproof grade through waterproof processing, and because interface 12 is small-size, even through long-time the use, can guarantee usually that its waterproof dustproof grade can not reduce.

With continued reference to fig. 1, an imaging system 15 is housed in the housing 11 to capture images via the capture window 13. The imaging system 15 includes an imaging unit 16 and a light supplement unit 17, the imaging unit 16 is used for imaging, and the light supplement unit 17 is used for supplementing light when the imaging unit 16 images. It is contemplated that other electronic components (not numbered, the same applies hereinafter) may be housed in the housing 11, such as a processor, a memory, etc., wherein the processor may decode images captured by the imaging system 15, and the memory may store data, etc., and will not be described further herein.

As shown in fig. 2, the housing 11 is coated with a heat-shrinkable film 2, and the heat-shrinkable film 2 seals the housing 11, so that even if the housing 11 deforms, the gap on the housing 11 is not communicated with the outside, and external moisture or dust cannot enter the interior of the handheld terminal 1 through the gap, which may damage internal electronic components. The heat-shrinkable film 2 is attached to the transparent sheets 14, so that the heat-shrinkable film 2 is prevented from forming a gap between the transparent sheets 14, and the transmittance of light is reduced. The heat-shrinkable film 2 is preferably made of PE, POF or other waterproof and antistatic materials, and meanwhile, the materials can be low-temperature resistant, for example, the POF heat-shrinkable film 2 can resist low temperature of-50 degrees, or the heat-shrinkable film 2 can be artificially subjected to antifogging treatment such as coating antifogging paint, or the heat-shrinkable film 2 directly made of antifogging materials is directly selected, in a word, the heat-shrinkable film 2 made of suitable materials can be selected for different use environments. If the material of the heat-shrinkable film 2 is thin and easy to damage, the heat-shrinkable film can be replaced frequently, or the material of the heat-shrinkable film 2 is thick and can be replaced once in a long time. Since the cost of the heat-shrinkable film 2 is very low, the cost of the heat-shrinkable film 2 covering one handheld terminal 1 is several corners or even several minutes, and the waterproof and dustproof performance of the handheld terminal 1 can be improved by the low-cost means.

The cladding of pyrocondensation membrane 2 accessible pyrocondensation machine (not shown in the figure, the same below) is in on the handheld terminal 1, and efficiency is very high, because pyrocondensation membrane 2 has the folding line usually, just pyrocondensation membrane 2 can form sealing line 21 when sealing, for avoid these lines to right imaging system 15 gathers the image and produces the influence, should avoid setting up these folding line or sealing line 21 in imaging system 15's the visual field, promptly the sealing line 21 or the folding line of pyrocondensation membrane 2 give way to imaging system 15's visual field.

For some special operational environment, improve through pyrocondensation membrane 2 the effect of handheld terminal 1's waterproof dustproof performance is especially obvious, for example the user can be before getting into the freezer, will through pyrocondensation membrane (or hot-blast section of thick bamboo) 2 cladding are in on the handheld terminal 1, pyrocondensation membrane 2 still can carry out antifog treatment, both isolated external steam, also make handheld terminal 1 can not the fogging when the precooling, avoids receiving the fogging influence when imaging system 15 gathers the image.

As shown in fig. 3 and 4, the handheld terminal 1 according to the second embodiment of the present application is different from the first embodiment in that: an opening 22 is preset on the heat shrinkage film 2 at a position corresponding to one interface 12 of the handheld terminal 1, so that the interface 12 is exposed, and the interface 12 may be a data line interface 12, a power supply interface 12, a memory card interface 12, or the like.

In other embodiments (not shown, the same applies below), the position of the heat shrinkage film 2 corresponding to the light supplement lamp may be colored to generate a light supplement with a specific color, and if the position of the heat shrinkage film 2 corresponding to the light supplement lamp is red and other positions are colorless, light emitted by the light supplement lamp is changed into red light after passing through the heat shrinkage film 2, it is known that the red light supplement can enhance the contrast between a barcode stripe and a background when a specific barcode is irradiated, so as to facilitate code scanning, so that a user may wrap the heat shrinkage film 2 on the handheld terminal 1 first when the user wants to scan the specific barcode, so that the light supplement lamp generates the specific color through the heat shrinkage film 2 when the user scans the specific barcode.

In other embodiments (not shown, the same applies below), the heat-shrinkable film 2 may be provided with the opening 22 at a position corresponding to the collecting window 13 to avoid light being blocked by the heat-shrinkable film 2.

In other embodiments (not shown, the same below), the handheld terminal 1 may be a handheld device such as an intercom, a mobile phone, a tablet computer, etc., the heat-shrinkable film 2 may be prefabricated into a shape matching the handheld terminal 1 in different shapes, and the opening 22 on the heat-shrinkable film 2 is preset to correspond to the interface 12 or the battery cover 18 on the handheld terminal 1, so as to facilitate the interface 12 to be plugged in for use or facilitate the battery cover 18 to be opened for replacing the battery, since a gap exists between a contact position for conducting the battery and the inside of the handheld terminal 1 in a battery compartment (for installing the battery, not shown, the same below), the range is extremely small, a very high waterproof level is easily achieved through waterproof treatment, and even if the heat-shrinkable film 2 does not cover the battery cover 18, the overall waterproof performance of the handheld terminal 1 can be improved.

The handheld terminal has the following beneficial effects:

1. the heat-shrinkable film 2 is coated on the shell 11 of the handheld terminal 1 through heat shrinkage, so that the waterproof and dustproof performance of the handheld terminal 1 is improved, the cost is low, the operation is easy, and the heat-shrinkable film is not only suitable for old equipment with lowered waterproof and dustproof grade, but also suitable for new equipment with originally low waterproof and dustproof grade.

2. An opening 22 is preset in the heat-shrinkable film 2 at the interface 12 on the housing 11, and after the heat-shrinkable film 2 is heat-shrunk and coated on the housing 11, the interface 12 is exposed at the opening 22, so that the interface 12 can be conveniently plugged and used, and meanwhile, the waterproof and dustproof performance of the handheld terminal 1 is also enhanced.

The above detailed description is only for the purpose of illustrating the preferred embodiments of the present application, and not for the purpose of limiting the scope of the present application, therefore, all technical changes that can be made by applying the present specification and the drawings are included in the scope of the present application.
