Abstract
The utility model provides a mobile point of sale terminal. The mobile point-of-sale terminal comprises a shell, a mobile point-of-sale system, a touch display panel, a sealant and at least two temperature sensors. The mobile point-of-sale system is disposed in the housing. The touch display panel is arranged on the shell. The sealant is disposed between the touch display panel and the housing. The encapsulant attaches the touch display panel to the housing. The at least two temperature sensors are arranged at least two corners of the shell and are positioned below the touch display panel. A tamper alarm is generated based on the detection results of the temperature sensors. Therefore, the temperature sensors sense the temperature change between the touch display panel and the sealing compound to generate a tamper warning so as to prevent the touch display panel from being abutted to protect information.
Description
Technical Field
The present invention relates to a mobile point-of-sale terminal (mobile POS terminal), and more particularly, to a mobile point-of-sale terminal including a temperature sensor.
Background
Prior art mobile point-of-sale terminals utilize conductive elements such as carbon granules or zebra stripes (zebra strips) to achieve a safety mechanism. Generally, one end of the conductive element is disposed to abut against a contact of a flexible board below the touch display panel, and the other end of the conductive element is disposed to abut against a contact of the main circuit board, so that a current path can be formed and a detection signal can be transmitted. Once the touch display panel is disassembled and lifted, the pressure provided to the conductive elements is insufficient. This will result in poor or no contact and will therefore trigger a safety mechanism.
However, the touch display panel continues to receive an upward force from the conductive element. Since the touch display panel is attached to the housing by the sealant, the touch display panel may be lifted up, which causes an appearance problem. In addition, the pressure applied to the conductive element may be weakened because the touch display panel is lifted up, so that a momentary break is more likely to occur when a shock occurs, and a safety mechanism may be erroneously triggered. Generally, a larger contact force provides more stable signal transmission, however, if the sealant cannot be firmly attached to the touch display panel, the touch display panel may be easily lifted. A small contact force may cause a momentary break during a drop deformation or in a shock environment.
Therefore, there is a need to design a new type of mobile point of sale terminal to overcome the above-mentioned drawbacks.

Detailed Description
In order to further understand the objects, structures, features and functions of the present invention, the following embodiments are described in detail.
Referring to fig. 1, 2, 3 and 4, an exemplary mobile point of sale terminal 10 is shown. Fig. 1 is a perspective view of a mobile point of sale terminal 10. Fig. 2 is a top view of the mobile point of sale terminal 10. Fig. 3 is a top view of the mobile point-of-sale terminal 10 after removal of the touch display panel 130. Fig. 4 is a cross-sectional view of an area a where the temperature sensor 150 is disposed.
The mobile point-of-sale terminal 10 includes a housing 110, a mobile point-of-sale system 120, a touch display panel 130, a sealant 140, and at least two temperature sensors 150. The mobile point-of-sale system 120 is disposed in the housing 110. The touch display panel 130 is disposed on the housing 110. The sealant 140 is disposed between the touch display panel 130 and the housing 110. The encapsulant 140 attaches the touch display panel 130 to the housing 110. The at least two temperature sensors 150 are disposed at least two corners of the housing 110 and located under the touch display panel 130.
The tamper alarm is generated according to the detection results of the temperature sensors 150. According to some embodiments, the tamper alert is generated when the detected temperature difference of any two of the temperature sensors 150 exceeds a predetermined value. In some embodiments, the value may be 15. For example, a tamper alert may be generated when one temperature sensor 150 detects a temperature T (where a Celsius temperature is used for T, T1, and T2, etc.) and another temperature sensor 150 detects a temperature greater than T +15 ℃. According to some embodiments, the tamper alert is generated when the detected temperature of any one of the temperature sensors 150 exceeds a predetermined temperature range. In some embodiments, where the mobile point of sale terminal 10 is designed to be used and stored at temperatures from T1 to T2, the predetermined temperature range for the temperature sensor 150 may be defined as (T1 x 110%) to (T2 x 110%). For example, the mobile point-of-sale terminal 10 is designed for use and storage at temperatures from T1 to T2, and the predetermined temperature range for the temperature sensor 150 may be defined as (T1-15 ℃) to (T2+15 ℃). It will be appreciated that the various embodiments provided herein with respect to triggering a tamper alert can be applied individually or in any possible combination, as desired.
According to some embodiments, the mobile point-of-sale terminal 10 may further include at least two thermally conductive materials 160 respectively disposed between the touch display panel 130 and corresponding ones of the temperature sensors 150, i.e., the thermally conductive materials 160 correspond to the temperature sensors 150 one-to-one. For example, the molding compound 140 may have a plurality of openings O corresponding to the temperature sensors 150, and the thermal conductive material 160 can be disposed in the openings O. The heat conductive material 160 may be a heat conductive pad or a heat conductive paste, etc., but the present invention is not limited thereto. The mobile point-of-sale terminal 10 includes at least two temperature sensors 150 disposed in at least two corners of the housing 110. When the number of the temperature sensors 150 is 2, 3, or 4, all of the temperature sensors 150 are disposed at different corners of the housing 110. However, it is understood that the temperature sensors 150 may not be all located at the corners of the mobile point-of-sale terminal 10. According to some embodiments, the temperature sensor 150 may be a Negative Temperature Coefficient (NTC) sensor or a thermistor, etc., but the present invention is not limited thereto. According to some embodiments, the temperature sensor 150 may be electrically connected to a circuit board 170 of the mobile point of sale terminal 10 also disposed in the housing 110. In some embodiments, the electrical connection is made by wires or flexible printed circuit boards, or the like. In some embodiments, some or all of temperature sensors 150 may be disposed directly on circuit board 170.
In summary, the mobile point-of-sale terminal provided by the utility model comprises a housing, a mobile point-of-sale system, a touch display panel, a sealant and at least two temperature sensors, wherein the mobile point-of-sale system is arranged in the housing; the touch display panel is arranged on the shell; the sealing glue is arranged between the touch display panel and the shell, and the sealing glue attaches the touch display panel to the shell; the at least two temperature sensors are arranged at least two corners of the shell and are positioned below the touch display panel; generating a tamper alarm according to the detection results of the temperature sensors. Since it is difficult to disassemble or lift the touch display panel of the mobile pos terminal only by force without damaging the structure of other parts, it is usually necessary to reduce the viscosity of the sealant by heating or quenching. Therefore, the change detection of the temperature sensor can be used as an effective safety mechanism to prevent the disassembly or lifting action. Although the above description is directed to the detachment and lifting of the touch display panel, the temperature sensor may be used to detect the detachment and lifting of other elements in a similar manner. The safety mechanism provided herein using temperature sensors is easy to implement. Furthermore, when the temperature sensor is used for the safety mechanism according to the embodiment, the touch display panel is not stressed as in the case of using the conventional conductive element, and thus the reliability problem of the attachment can be prevented.
