Description

Technical Field

[0001] This utility model relates to the technical field of touch screens, and specifically to a touch screen panel. Background Technology

[0002] Touchscreens, as an efficient and intuitive human-computer interaction interface, have been widely used in many fields such as smartphones, tablets, industrial control equipment, self-service terminals, and smart home control panels.

[0003] Touchscreen panels generate a lot of heat during continuous operation, especially when displaying high brightness or performing complex graphics calculations. If this heat cannot be dissipated in time, the panel temperature will rise significantly. Excessive panel temperature can cause a series of problems, such as slowing down the response speed of the liquid crystal material, resulting in touch response delay or display ghosting, which affects the user experience. Secondly, high temperature will accelerate the aging of electronic components and optical materials inside the panel, shortening the lifespan of the device. In extreme cases, overheating may even trigger the device's protection mechanism, causing automatic shutdown and affecting the device's continuous working capability.

[0004] Common touchscreen heat dissipation methods mainly rely on passive heat dissipation, but natural heat dissipation is inefficient and cannot cope with the concentrated heat generated by high-power devices. The heat cannot be effectively guided to the outside of the device, resulting in poor heat dissipation. Utility Model Content

[0005] This utility model aims to solve the technical problem of poor heat dissipation in existing touch screens.

[0006] To solve the above-mentioned technical problems, the purpose of this utility model can be achieved through the following technical solution: a touch screen panel, including a panel body, a heat-conducting plate fixedly connected to the back of the panel body, two partitions fixedly connected to the side of the heat-conducting plate away from the panel body, and heat dissipation vents provided at the top and bottom of the panel body, the heat-conducting plate, partitions and heat dissipation vents forming a vertical heat dissipation channel.

[0007] As a further embodiment of this utility model: the heat-conducting plate is provided with a plurality of heat-conducting fins located between the two partitions, the plurality of heat-conducting fins are distributed sequentially at intervals along a direction perpendicular to the partitions, and the extension direction of each heat-conducting fin is consistent with the extension direction of the partition.

[0008] As a further embodiment of this utility model: the panel body is mounted on the mounting plate, and multiple slots are provided on both sides of the back of the panel body. Multiple trapezoidal protrusions are provided on the mounting plate, and the slots and trapezoidal protrusions cooperate with each other to achieve snap-fit.

[0009] As a further embodiment of this utility model: elastic protrusions are provided on both sides of the trapezoidal protrusion, and the inner wall of the slot is provided with a groove adapted to the elastic protrusion, and the elastic protrusion engages with the groove.

[0010] As a further embodiment of this utility model: a heat-conducting layer is provided between the panel body and the heat-conducting plate, and the heat-conducting layer is a graphene heat-conducting film.

[0011] As a further embodiment of this utility model, a detachable dustproof mesh is provided at the heat dissipation vent.

[0012] As a further embodiment of this utility model: a sealing ring is provided on the back edge of the panel body, and when the panel body is installed on the mounting plate, the sealing ring is compressed between the panel body and the mounting plate.

[0013] As a further aspect of this invention, the cross-sectional size of the heat dissipation channel is the same as the size of the heat dissipation opening.

[0014] As a further embodiment of this utility model: the two partitions are arranged vertically and are parallel to each other.

[0015] As a further embodiment of this utility model: the heat-conducting layer extends to the edge of the heat dissipation port, forming a thermal bridge connection with the heat dissipation channel.

[0016] The beneficial effects of this utility model are: 1. When the heating element on the back of the panel is working, the heat is conducted through the heat-conducting plate to the vertical heat dissipation channel on the back. The heat dissipation channel is like a heat collection pipe, concentrating the heat dispersed in various places on the back of the panel into the channel, avoiding the random diffusion of heat and the formation of local hot spots. The partition guides the natural flow of hot air. Taking advantage of the physical properties that hot air has a lower density and naturally flows upward, while cold air has a higher density and naturally flows downward, the air in the channel absorbs heat and naturally flows upward along the vertical heat dissipation channel. The hot air can be directly discharged from the top opening to the outside of the panel without being blocked or stagnated by the panel body. When the hot air is discharged from the top, a low-pressure area will be formed in the heat dissipation channel. At this time, the cold air outside the panel will automatically enter the heat dissipation channel through the bottom heat dissipation vent, and then heat up again, flow upward, and be discharged from the top. This forms a continuous heat dissipation cycle, thereby improving the heat dissipation effect. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-3 As shown, this utility model is a touch screen panel, including a panel body 1. A heat-conducting plate 8 is fixedly connected to the back of the panel body 1. Two partitions 6 are fixedly connected to the side of the heat-conducting plate 8 away from the panel body 1. Heat dissipation vents 9 are provided at the top and bottom of the panel body 1. The heat-conducting plate 8, partitions 6 and heat dissipation vents 9 form a vertical heat dissipation channel 5. The cross-sectional size of the heat dissipation channel 5 is the same as the size of the heat dissipation vents 9. The heat generated by the heating element on the back of the touch screen is transferred to the heat dissipation channel 5 through the heat-conducting plate 8. The heat is then guided to the heat dissipation vents 9 by the partitions 6 on both sides and the heat-conducting plate 8. The vertical heat dissipation channel 5 follows the natural convection law of hot air rising and cold air sinking. It is especially suitable for touch screens that rely on passive heat dissipation, i.e., without fans. The hot air generated by the heating element on the back of the touch screen will naturally flow upward. The hot air can rise quickly along the channel and be discharged. At the same time, the cold air at the bottom will fill the channel, forming a continuous upward convection cycle. Stable heat dissipation can be achieved without additional power.

[0022] In another embodiment, both ends of the heat-conducting plate 8 and the partition plate 6 abut against the heat dissipation vents 9 at the top and bottom of the panel body 1, so that the heat dissipation channel 5 cannot be connected to the inside of the touch screen. At this time, the heat is transferred to the heat dissipation channel 5 by the heat-conducting plate 8 alone. Although the heat dissipation effect is reduced, since the heat dissipation channel 5 cannot be connected to the inside of the touch screen, the dust that enters from the heat dissipation vent 9 at the top of the panel body will be directly discharged from the heat dissipation vent 9 at the bottom, thereby improving the dustproof effect. This is suitable for scenarios where the heat dissipation requirements are not high, but the dustproof requirements are high.

[0023] In another embodiment, the heat-conducting plate 8 is provided with a plurality of heat-conducting fins 7 located between the two partitions 6. The plurality of heat-conducting fins 7 are distributed sequentially at intervals along a direction perpendicular to the partitions 6, and the extension direction of each heat-conducting fin 7 is consistent with the extension direction of the partition 6. The function of the heat-conducting fins 7 is to accelerate heat dissipation by increasing the surface area. The surface of the heat-conducting fins 7 is covered with a nano carbon coating, which can reduce the thermal resistance of the surface of the heat-conducting fins 7 and enhance the heat exchange efficiency between the heat-conducting fins 7 and the air, which is especially suitable for the heat dissipation requirements of high-power touch screens. In another embodiment, the panel body 1 is mounted on the mounting plate 2. Multiple slots 3 are provided on both sides of the back of the panel body 1. Multiple trapezoidal protrusions 4 are provided on the mounting plate 2. The slots 3 and the trapezoidal protrusions 4 cooperate with each other to achieve a snap-fit. The trapezoidal protrusions 4 are provided with elastic protrusions 11 on both sides. The inner wall of the slot 3 is provided with a groove that matches the elastic protrusions 11. The elastic protrusions 11 snap-fit ​​with the groove. The trapezoidal structure can avoid lateral misalignment after snap-fit ​​and improve the connection stability.

[0024] In another embodiment, a thermally conductive layer is provided between the panel body 1 and the heat-conducting plate 8. The thermally conductive layer is made of graphene or silicone thermal pad and has a thickness of 0.1-0.5mm. The panel body 1 is the main heat source. The circuit and display module of the touch screen generate heat when it is working. The heat-conducting plate 8 is the core carrier of the heat dissipation channel 5. By adding a thermally conductive layer between the two, the contact gap between the panel body 1 and the heat-conducting plate 8 can be eliminated. The heat of the panel body 1 is efficiently conducted to the heat-conducting plate 8 through the high thermal conductivity material, and then dissipated through the heat dissipation channel 5 and the heat-conducting fins 7, which significantly improves the heat transfer efficiency.

[0025] In another embodiment, the thermally conductive layer extends to the edge of the heat dissipation vent 9 and forms a thermal bridge connection with the heat dissipation channel 5. There may be local heat accumulation in the area on the back of the panel body 1 other than the heat dissipation channel 5. By setting the thermally conductive layer and extending it to the heat dissipation vent 9, the heat at the edge can be guided to the heat dissipation channel 5 and the heat dissipation vent 9, avoiding local overheating and forming a global heat dissipation network. This position makes up for the limitation of the heat dissipation channel 5 only covering the central area and expands the coverage of the heat dissipation path.

[0026] A detachable dustproof net 10 is provided at the heat dissipation vent 9. The dustproof net 10 is made of nylon and is detachably connected to the heat dissipation vent 9 by a buckle, which facilitates regular removal and cleaning of the dustproof net 10 and prevents dust from clogging the heat dissipation vent 9. A sealing ring is provided on the back edge of the panel body 1. When the panel body 1 is installed on the mounting plate 2, the sealing ring is compressed between the panel body 1 and the mounting plate 2.

[0027] In another embodiment, the touch screen panel further includes a touch module, a main control module, an interface module, a display module, and a software system; The touch module integrates a touch panel and a touch controller. The touch panel is used to receive user touch operations. When the user touches the touch panel, the touch module detects the touch position in real time and generates a corresponding touch electrical signal. After the touch controller performs preliminary processing on the touch electrical signal, it transmits the processed touch electrical signal to the main control module through a preset signal transmission line to trigger subsequent command responses. The main control module is the core control unit of the touch panel. After receiving the touch electrical signals transmitted by the touch module, it parses the touch electrical signals to determine the user's operation intention. If the parsing result is to call the historical data query function in the application, the main control module sends a data request signal to the external battery management system through the internal communication interface to obtain the target historical data according to the preset interaction logic. At the same time, the main control module is also responsible for monitoring and scheduling the working status of each module to ensure the overall functional coordination.

[0028] The interface module establishes a data connection with the main control module and the external BMS. When the external BMS responds to the data request signal sent by the main control module and returns historical data, the interface module receives the historical data through the RS485 bus or CAN bus, performs format adaptation on the data, and then transmits the adapted historical data to the main control module through the data transmission line, thus completing the transfer of external data to the internal system.

[0029] The display module integrates an LCD screen and a display driver unit, establishing a bidirectional connection with the main control module for control and data signals. After receiving historical data transmitted from the interface module, the main control module processes the data and converts it into a chart or table format that meets display requirements. Subsequently, the main control module sends display control commands and the processed data to the display module. The display driver unit responds to the control commands, drives the LCD screen to render the data, and visualizes the historical data results and module operating status information for user viewing.

[0030] The software system comprises an embedded operating system and application layer programs. The embedded operating system is used to schedule the hardware resources of the touch panel, specifically including: touch signal detection resources for the touch module, instruction parsing and data processing resources for the main control module, bus communication resources for the interface module, and screen driver resources for the display module. Through dynamic allocation and priority management of resources, the system ensures the real-time performance of touch signal transmission, external data interaction, data processing, and screen display, avoiding functional delays caused by resource contention. The application layer programs encapsulate functional modules for historical data query, status monitoring, and alarm handling, providing interactive logic support for user operation.

[0031] The working principle of the touch screen panel involved in this utility model is as follows: The mounting plate 2 is installed on the wall. The panel body 1 is installed on the mounting plate 2 by the interlocking of the slot 3 and the trapezoidal protrusion 4. At the same time, the elastic protrusion 11 can be engaged with the groove in the slot 3, thereby further stabilizing the panel body 1. The back of the panel body 1 is equipped with the heating element of the controller chip and display driver. The heating element transfers heat to the heat conduction plate 8 through the heat conduction layer. The heat conduction plate 8 transfers heat to the heat dissipation channel 5. Since the heat dissipation channel 5 is set vertically, hot air can be discharged from the heat dissipation vent 9 at the top of the panel body 1, while cold air enters from the heat dissipation vent 9 at the bottom of the panel body 1, forming a heat dissipation cycle, thereby improving the heat dissipation effect.

[0032] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
