Technical Field
[0001] This utility model relates to the field of touch screen controller technology, and more specifically, to a controller based on a TFT touch screen. Background Technology
[0002] A smart barbecue grill is a type of barbecue equipment that integrates modern technology, enabling automation and intelligent operation of the grilling process. For example, a touchscreen electric grill gets its name from its touchscreen control switch. Like other electric grills, touchscreen electric grills use electric heating elements, but unlike others, these elements are located on both sides of the grill's interior. This prevents grease from dripping onto the heating elements and creating smoke. A TFT (Thin Film Transistor) touchscreen controller is an electronic component used to control and manage the TFT touchscreen display. TFT touchscreens typically consist of a liquid crystal display (LCD) and a touch-sensitive layer, and are widely used in smart industrial equipment, automotive dashboards, and other electronic devices. TFT touchscreen controllers are popular due to their high resolution, energy efficiency, environmental friendliness, and ease of operation.
[0003] Among them, the patent with announcement number CN216253403U discloses a touch screen controller structure, including a controller housing, a touch screen, control buttons, and a rotating mechanism. The control housing includes a bottom housing and a cover. The bottom housing and the cover are fixed by a connecting buckle. The rotating mechanism is connected and fixed to the side of the bottom housing. The touch screen is fixed at the cover. An alarm flashing light is also provided on the side of the bottom housing. A protective device is provided between the touch screen and the cover.
[0004] When in use, the control panel housing with protective devices makes the overall controller structure more stable. After the touch screen is installed, its position can be adjusted, and the overall direction can be controlled by the rotation mechanism. However, when the device is running, the touch screen usually generates a lot of heat due to the working environment and external temperature. The heat cannot be dissipated quickly, which can easily cause the touch screen to freeze. At the same time, it is not easy to quickly sort out different wires, making wiring inconvenient. Utility Model Content
[0005] To achieve the above objectives, this utility model provides the following technical solution: a controller based on a TFT touch screen, comprising an aluminum shell, on which a cable management and heat dissipation assembly is disposed;
[0006] The cable management and heat dissipation assembly includes a heating baffle on one side of the aluminum shell, two support frames on the heating baffle, and a heat sink is bolted to each support frame. A processor is bolted between the aluminum shell and the heating baffle.
[0007] One end of the aluminum shell is provided with a plurality of first limiting ports, and the bottom of each of the first limiting ports is provided with a plurality of second limiting ports. One side of the surface of each of the first limiting ports and the second limiting ports is provided with an identification fixed on the aluminum shell. A first constraint member is engaged in each of the plurality of first limiting ports, and a second constraint member is engaged in each of the plurality of second limiting ports.
[0008] As can be seen, in the above technical solution, the wires are connected to the first constraint and the second constraint respectively. The markings prevent incorrect wiring. The processor is responsible for controlling the pixels of the display to ensure the correct display of the image and to recognize the user's touch operations, such as clicking, swiping, zooming, etc.
[0009] Optionally, in one possible implementation, a plurality of heat dissipation aluminum rods are provided on the outer side of the processor, and each of the heat dissipation aluminum rods is fixed on the aluminum shell. One end of each of the heat dissipation aluminum rods is threaded with a rubber post, and one end of each rubber post extends to one side of the heating baffle. A plurality of flow guide holes are provided through the upper surface of the aluminum shell, and a switch is provided on one side of the surface of the flow guide holes. The switch is installed on the aluminum shell. A slot is provided at the bottom of the heating baffle. A protrusion is fixedly provided at the bottom of the aluminum shell. The protrusion matches the slot and the protrusion engages with the slot.
[0010] As can be seen, in the above technical solution, the airflow is drawn in after the heat sink is activated. The external airflow enters between the aluminum shell and the heating baffle through the guide hole and carries away the heat. The heat dissipation aluminum rod conducts heat from the processor and the touch screen to the aluminum shell, which facilitates the rapid dissipation of heat and avoids the phenomenon of the touch screen freezing due to the inability to dissipate heat.
[0011] The technical effects and advantages of this utility model are as follows:
[0012] By setting up a cable management and heat dissipation component, compared with the existing technology, through the corresponding cooperation of various structures, the wires are connected to the first constraint and the second constraint respectively. The markings prevent incorrect wiring during the wiring process. The processor is responsible for controlling the pixels of the display to ensure the correct display of the image and to recognize the user's touch operations, such as clicking, swiping, zooming, etc.
[0013] After the heat sink is activated, airflow is drawn in. The external airflow enters between the aluminum shell and the heating baffle through the guide hole and carries away the heat. The heat dissipation aluminum rod conducts heat from the processor and touch screen to the aluminum shell, which facilitates the rapid dissipation of heat and prevents the touch screen from freezing due to the inability to dissipate heat. The position of the rubber column is adjusted so that it can abut against the heating baffle. When the heating baffle is subjected to force, the rubber column absorbs energy and reduces the force, preventing external forces from damaging the device. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] As attached Figure 1-4 The controller shown is based on a TFT touch screen. Through the cable management and heat dissipation assembly set on the aluminum shell 1, the wires are respectively connected to the first constraint member 7 and the second constraint member 8. The marking 6 prevents the wires from being connected incorrectly. The heat sink 12 is activated to draw airflow. The external airflow enters between the aluminum shell 1 and the heating baffle 2 through the guide hole 13 to carry away the heat. The heat dissipation aluminum rod 9 conducts the heat transferred from the processor 3 and the touch screen to the aluminum shell 1, which facilitates the rapid dissipation of heat and avoids the phenomenon of the touch screen freezing due to the inability to dissipate heat. The specific structure of the component is as follows.
[0022] The cable management and heat dissipation assembly includes a heating baffle 2 disposed on one side of the aluminum shell 1, two support frames 11 disposed on the heating baffle 2, and a heat sink 12 is bolted to each support frame 11. A processor 3 is bolted between the aluminum shell 1 and the heating baffle 2.
[0023] One end of the aluminum shell 1 is provided with a number of first limiting ports 4, and the bottom of each first limiting port 4 is provided with a number of second limiting ports 5. The surface of the first limiting port 4 and the second limiting port 5 are provided with a mark 6 fixed on the aluminum shell 1. A first constraint member 7 is engaged in the multiple first limiting ports 4, and a second constraint member 8 is engaged in the multiple second limiting ports 5.
[0024] The processor 3 has several heat dissipation aluminum rods 9 on its outer side, and each heat dissipation aluminum rod 9 is fixed on the aluminum shell 1. One end of each heat dissipation aluminum rod 9 is threaded with a rubber post 10, and one end of each rubber post 10 extends to one side of the heating baffle 2. Several guide holes 13 are opened through the upper surface of the aluminum shell 1, and a switch 14 is provided on one side of the surface of the guide hole 13. The switch 14 is installed on the aluminum shell 1. A slot 15 is opened at the bottom of the heating baffle 2. A protrusion 16 is fixedly provided at the bottom of the aluminum shell 1. The protrusion 16 matches the slot 15 and the protrusion 16 is engaged with the slot 15.
[0025] According to the above structure, when in use, the staff will connect the wires on the touch screen to the first constraint 7 and the second constraint 8 respectively. The marking 6 will prevent the wires from being connected incorrectly. The processor 3 is responsible for controlling the pixels of the display to ensure the correct display of the image. This includes updating the image, adjusting the color and controlling the brightness. The controller also processes the input signals from the touch screen, recognizes the user's touch operations such as clicking, swiping, zooming, etc., and feeds them back to the processor 3.
[0026] Meanwhile, when the device is running, the heat sink 12 is activated to draw airflow. The external airflow enters between the aluminum shell 1 and the heating baffle 2 through the guide hole 13 and carries away the heat. The heat dissipation aluminum rod 9 conducts heat from the processor 3 and the touch screen to the aluminum shell 1, which facilitates the rapid dissipation of heat and avoids the phenomenon of the touch screen freezing due to the inability to dissipate heat.
[0027] Furthermore, the rubber column 10 is threadedly connected to the heat dissipation aluminum rod 9. Adjusting the position of the rubber column 10 allows it to contact the heating baffle 2, making it easier for the rubber column 10 to absorb energy and reduce the force when the heating baffle 2 is subjected to force, thus preventing external forces from damaging the device.
[0028] Unlike existing technologies, this application discloses a controller based on a TFT touch screen. The controller is connected to the first constraint member 7 and the second constraint member 8 by wires. The markings 6 prevent incorrect wiring. The heat sink 12 draws in airflow, which enters the space between the aluminum shell 1 and the heating baffle 2 through the guide holes 13 to remove heat. The heat sink 9 conducts heat from the processor 3 and the touch screen to the aluminum shell 1, which facilitates rapid heat dissipation and prevents the touch screen from freezing due to heat not being dissipated.
[0029] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
