Description

Technical Field

[0001] The utility model relates to the technical field of ink screens, and in particular to an ink screen structure suitable for use in low-temperature environments. Background Art

[0002] The ink screen technology uses electric fields to control the movement of tiny particles to achieve image display, and has two major characteristics: bistable and reflective. The bistable technology allows the ink screen to continue to display the image after the power source is removed, and only consumes power when the image is changed, thus achieving extremely low energy consumption. The reflective technology allows the ink screen to display clearly in the sun without backlight, and is harmless to the eyes, suitable for long-term reading. However, the realization of these technical advantages is highly dependent on the appropriate working environment temperature.

[0003] At present, the normal operating environment temperature range of commercial mass-produced ink screen products is usually limited to between 0 and 50 degrees. This limitation is mainly due to the fact that the viscosity coefficient of the liquid in the microcapsules inside the ink screen increases as the temperature decreases, which causes the movement of ink particles under the action of the electric field to be hindered, thereby affecting the display effect. Specifically, when the temperature is below 0 degrees and gradually decreases, the response speed of the ink screen becomes significantly slower, and the displayed content gradually fades until only the background color remains and no longer refreshes.

[0004] In northern my country, the outdoor temperature is below zero for a long time in winter, which directly leads to the inability of e-ink bus stops to function normally in these areas. Due to the failure of e-ink screens at low temperatures, passengers are unable to obtain key information such as bus routes and arrival times in a timely manner, which seriously affects the service quality of public transportation and the travel experience of passengers.

[0005] Therefore, an ink screen structure suitable for low temperature environments is proposed. Utility Model Content

[0034] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0035] An ink screen structure suitable for use in a low temperature environment, comprising:

[0036] Reference Figure 1 , ink screen 1, heating film 2, buffer 3, sheet metal component 4, shell 5, circuit element 6; the outer side of the shell 5 is rounded to prevent the corners from being too sharp and causing injuries to people or objects. The ink screen 1 is attached to one side of the heating film 2, refer to Figure 2 The heating film 2 includes a film body 21, a copper strip 22, and a temperature sensor 23; the film body 21 is embedded with the temperature sensor 23 and the copper strips 22 arranged at equal intervals, and the copper strips 22 arranged at equal intervals ensure uniform and accurate heat distribution, and the circuit element 6 supplies power to the temperature sensor 23 through the tabs of the copper strips 22 and controls the temperature of the temperature sensor 23. The heating film 2 can be a PET heating film, which can achieve a fast and uniform heating effect by cooperating with the circuit element 6, and can effectively reduce energy loss due to its good thermal insulation performance.

[0037] The other side of the heating film 2 is attached to one side of the buffer 3. The buffer 3 includes an EVA sponge. The EVA sponge layer has the advantages of good buffering, shock resistance, heat insulation, moisture resistance, chemical corrosion resistance, antibacterial and waterproof, and is non-toxic. The other side of the buffer 3 is fixed to the shell 5 through a sheet metal component 4. The sheet metal component 4 and the shell 5 are locked by screws. The side of the sheet metal component 4 facing away from the buffer 3 is connected to the circuit element 6. The sheet metal component 4 ensures the stability of the overall structure.

[0038] The glass layer 7 is embedded in the outer shell 5, and a shock-absorbing component 9 is provided on an inner side of the sheet metal component 4 close to the outer shell 5. The shock-absorbing component 9 includes an EVA sponge component. The side of the shock-absorbing component 9 away from the sheet metal component 4 is bonded to the glass layer 7. A first space 8 is formed between the shock-absorbing component 9 and the outer shell 5. The thickness of the shock-absorbing component 9 after compression is greater than the sum of the thickness of the glass layer 7 and the thickness of the ink screen 1, so that a second space 10 is formed between the glass layer 7 and the ink screen 1. The first space 8 and the second space 10 not only provide additional buffering protection for the ink screen 1, but also effectively isolate the cold air that may invade from the outside of the glass layer 7. Of course, when the temperature of the ink screen 1 is too high, the first space 8 and the second space 10 can also help the ink screen 1 to dissipate heat better and maintain its stable operation.

The first contact plate 411, the mounting plate 412, and the first connecting plate 413 are integrally formed. One side of the first contact plate 411 is in contact with the shock absorber 9, and one end of the first contact plate 411 is connected to one end of the mounting plate 412; one end of the mounting plate 412 is connected to one end of the first connecting plate 413, the first connecting plate 413 is connected to one side of the thermal insulation pad 11, and the other side of the thermal insulation pad 11 is connected to the housing 5; the first connecting plate 413 is connected to the second sheet metal part 42. The second sheet metal part 42 includes a second connecting plate 421 and a second contact plate 422. The second connecting plate 421 and the second contact plate 422 are integrally formed. The second connection plate 421 is connected to the first connection plate 413, the first connection plate 413 and the second contact plate 422 are arranged at a right angle, one surface of the second contact plate 422 is in contact with the buffer 3, and the other surface of the second contact plate 422 is connected to the circuit element 6. The first contact plate 411 is arranged parallel to the glass layer 7, and the mounting plate 412 is arranged at a right angle to the first contact plate 411 and fixed to the inner side of the housing 5.

[0040] The waterproof strip 12 is arranged at the junction of the outer shell 5 and the glass layer 7 . The waterproof strip 12 can reduce the possibility that water mist enters the inner part through the gap when the outer shell 5 and the glass layer 7 are not tightly connected, thereby damaging the ink screen 1 .

[0041] In summary, the present application includes at least one of the following beneficial technical effects:

[0042] 1. Through the built-in heating film, combined with the precise control of circuit components, it can provide a stable heating effect for the e-ink screen in a low temperature environment, preventing display abnormalities caused by too low temperature (such as slow response speed, faded display content, etc.), ensuring the normal operation of the e-ink screen in extremely cold conditions, and breaking through the bottleneck of low temperature limitation of traditional e-ink screens.

[0043] 2. The temperature sensor embedded in the heating film can monitor the temperature changes of the ink screen in real time and feed back the signal to the circuit components, thereby realizing dynamic temperature adjustment, which not only improves the response speed of the system, but also ensures the consistency and stability of the display effect under different low temperature conditions.

[0044] 3. The first space and the second space not only provide additional buffer space for the ink screen, but also play a good heat insulation role, effectively isolating the intrusion of external cold air, maintaining the relative stability of the internal temperature of the ink screen, and reducing the impact of temperature fluctuations on the display effect.

[0045] 4. The ink screen is not subjected to pressure in the entire structure, which reduces the possibility of the ink screen breaking due to accidental pressure during assembly and use.

[0046] 5. During long-term use, the waterproof strip has a greater chance of being damaged and never loses its waterproofing function. The EVA sponge layer absorbs water, thereby improving the waterproof performance of this application.
