Description

Technical Field

[0001] This utility model relates to the field of electronic equipment technology, and more specifically, to a touch control keyboard. Background Technology

[0002] With the development of electronic devices, touch control keyboards are widely used in various devices. Touch control keyboards include a base and a touch screen located on the top of the base. The touch screen has a touch area, and users can use their fingers to slide, click, and perform other operations on the touch area to achieve functions such as clicking, moving, and scrolling like a mouse, thereby reducing dependence on an external mouse.

[0003] However, during the use of touch-controlled keyboards, the touchscreen and motherboard generate a significant amount of heat. Traditional cooling methods require thermal grease to be filled between the heat source and the heat dissipation surface as a thermal medium. The heat dissipation relies on the thermal grease, not the heat dissipation material itself. As the thermal medium ages, its thermal resistance increases, and the medium itself becomes a thermal bottleneck. Poor heat dissipation will lead to decreased keyboard performance or even damage to the keyboard, and also presents difficulties for future assembly and maintenance. Summary of the Invention

[0004] This utility model provides a touch control keyboard that, through structural components such as a touch screen, aluminum plate components, adapter frame components, and bottom cover components, can overcome the shortcomings of insufficient heat dissipation function in existing control keyboards.

[0005] To solve the aforementioned technical problems, this utility model adopts the following solution:

[0006] A touch control keyboard includes a touch screen assembly, which comprises a touch screen and an aluminum plate component for mounting the touch screen. The touch screen has a touch controller that protrudes outwards from its bottom. The keyboard also includes a bottom cover component and a transition frame component for mounting the touch screen assembly onto the bottom cover component. The aluminum plate component is a plate-shaped aluminum alloy substrate with a touch screen mounting groove on its upper surface. A downwardly recessed air groove is provided on the bottom wall of the touch screen mounting groove, and several heat-conducting protrusions are provided on the air groove. The bottom cover component includes a bottom cover housing with an open upper end. A bottom cover ventilation hole is provided on the lower bottom wall of the bottom cover housing, and a control main board is located at the bottom cover ventilation hole.

[0007] Furthermore, both the touch controller and the air slot are square. When the touch screen is installed in the touch screen mounting slot, the air slot is located directly below the touch controller. The air slot is provided with several heat-conducting bumps. The top of the heat-conducting bumps is attached to the bottom of the touch controller. The heat of the touch component is evenly conducted to the aluminum plate component through the heat-conducting bumps, and then dissipated by the aluminum plate component.

[0008] Furthermore, an LED circuit board mounting slot is provided on the aluminum plate component and located at the bottom wall of the touch screen mounting groove, and an LED display board is installed in the LED circuit board mounting slot; the LED display board can be fixed on the aluminum plate component through the LED circuit board mounting slot.

[0009] Furthermore, the LED display panel includes a fixing part and an LED display part that are perpendicularly arranged and both are elongated. The fixing part is fixed to the bottom wall of the LED circuit board mounting groove by screws. The LED display part is equipped with a plurality of LED beads that are spaced apart along the length of the LED display part. The LED display part is also equipped with light guide columns disposed at the LED beads. Compared with traditional LED beads, LED beads require less energy to produce bright light, thus improving luminous efficiency. The addition of light guide columns allows the light from the LED display panel to be refracted onto the touch screen evenly and softly, and also improves the brightness of the light source, effectively reducing power consumption.

[0010] Furthermore, the LED circuit board mounting groove includes a fixing groove and a mounting groove that cooperate with the fixing part and the LED display part respectively. The lower part of the mounting groove is constructed as an elongated groove that cooperates with the LED display part, and the upper part is constructed as an upper light guide post fixing groove that cooperates with the light guide posts one by one.

[0011] Furthermore, the adapter frame component includes a rectangular frame for mounting the aluminum plate component. The upper surface of the rectangular frame forms a mounting plane, and a connecting piece extending downward is provided at the lower edge of the rectangular frame. The adapter frame component is connected to the bottom cover component through the connecting piece. This connection method facilitates disassembly and is beneficial for the long-term maintenance of the touch control keyboard.

[0012] Furthermore, the connecting piece is uniformly provided with a plurality of first screw holes for connecting with the bottom cover housing, and the mounting plane is uniformly provided with a plurality of second screw holes for fixing the aluminum plate components; this installation method has a short processing cycle, low cost, and is convenient for maintenance and disassembly.

[0013] Furthermore, it also includes a joystick controller. The touch screen and the aluminum plate component have joystick control guide holes through which the joystick controller passes. The joystick controller is fixed to the aluminum plate component and its bottom passes through the rectangular frame. The remote sensing control guide holes serve a positioning function, so that the joystick controller and the touch screen are on the same vertical axis.

[0014] Furthermore, a fixing post is installed on the inner side of the bottom wall of the bottom cover housing, located at the edge of the bottom cover ventilation hole. The control motherboard is fixed on the fixing post. The bottom cover ventilation hole includes multiple evenly arranged rectangular mesh holes. Multiple fixing posts are evenly distributed at the edge of the bottom cover ventilation hole. The fixing posts are set vertically upward to form a ventilation gap between the control motherboard and the mesh plate. The chip of the control motherboard is located at the bottom cover ventilation hole. The heat generated by the chip is dissipated by the air. The fixing posts of the bottom cover have a certain height. In addition to fixing the control motherboard, the specific height guides the cold air to flow along the bottom cover ventilation hole in multiple groups, and the air flows in a superimposed form in the horizontal and vertical directions to carry away the heat of the chip.

[0015] Furthermore, a bottom cover protrusion is provided on the outer side of the bottom wall of the bottom cover housing, and a circular rubber sheet is fitted on the bottom of the bottom cover protrusion; the circular rubber sheet is made of hard granular rubber, which increases the friction of the keyboard on the flat surface and plays a role in preventing slippage.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] By setting up an aluminum plate component, the heat generated during the operation of the touch control keyboard can be absorbed and conducted. The square heat-conducting bumps are arranged in a highly dense matrix topology. The top plane of each bump is precision milled to form a multi-node direct metal contact with the heat-generating area of ​​the touch component. The micro gaps at the contact interface are eliminated by the statistical mechanical compensation principle, so that the heat flow can be efficiently introduced into the aluminum plate component through the bump body without the need for a heat-conducting medium. In addition, the air groove receives part of the heat source of the touch component and forms a cold and heat flow exchange with the first and second wire holes using air.

[0018] The bottom cover component is equipped with bottom cover ventilation holes. The bottom cover fixing column is at a certain height from the inner bottom wall of the bottom cover. The specific height guides the cold air to flow along multiple sets of bottom cover ventilation holes, carrying away the heat of the chip and improving heat dissipation performance.

Detailed Implementation

[0027] 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.

[0028] Please see Figure 1-7 This embodiment provides a touch control keyboard, including a touch screen 1, an aluminum plate component 2, an adapter frame component 4, and a base cover component 6.

[0029] The touchscreen is a 10.1-inch touchscreen with specification model CTP-1010-357. A touch area 101 is formed on the touchscreen 1. A touch controller 102 protrudes outward from the bottom of the touchscreen 1. The back of the touchscreen 1 also has a first cable outlet 103 and a second cable outlet 104. The aluminum plate component 2 is a plate-shaped aluminum alloy substrate with a touchscreen mounting groove 203 on its upper surface for mounting the touchscreen. An air groove 204 corresponding to the touch controller 102 is provided on the bottom wall of the touchscreen mounting groove 203. A heat-conducting protrusion 206 is provided at the air groove 204, and a first wire passage hole 207 and a second wire passage hole 208 are also provided on the aluminum plate component 2. The first exit wire 103 and the second exit wire 104 of the touch screen 1 pass through the first wire passage hole 207 and the second wire passage hole 208 and are connected to the control motherboard 5. The first wire passage hole 207 and the second wire passage hole 208 are located at the bottom wall of the air groove 204. In addition to the task of wire passing, the first wire passage hole 207 and the second wire passage hole 208 also provide airflow channels to form convection with the air in the air groove 204.

[0030] The adapter frame component 4 is used to mount the touch screen on the base cover component 6. The adapter frame component 4 includes a rectangular frame 40 for mounting the aluminum plate component 2. The upper end surface of the rectangular frame 40 forms a mounting plane 401. A connecting piece 402 extending downward is provided at the lower edge of the rectangular frame 40. The adapter frame component 4 is connected to the base cover component 6 through the connecting piece 402.

[0031] The bottom cover component 6 includes a bottom cover housing 60 with an opening at the top. A bottom cover ventilation hole 601 is provided at the bottom wall of the bottom cover housing 60. A fixing post 602 is installed on the inner side of the bottom wall of the bottom cover housing 60 and at the edge of the bottom cover ventilation hole 601. A control motherboard 5 with a touch control keyboard is fixed on the fixing post 602.

[0032] After the touch screen 1, aluminum plate component 2, adapter frame component 4 and bottom cover component 6 are assembled, the touch screen 1 is located in the touch screen mounting slot 203. The upper surface of the aluminum plate component 2 corresponds to the touch screen 1, and the lower surface of the aluminum plate component 2 corresponds to the bottom cover component 6. Part of the lower surface and the side are exposed to the air. When the touch screen 1 is running, the touch controller 102 will generate heat. The aluminum plate component 2 will quickly absorb and conduct heat to the areas where the heat is concentrated, thereby achieving the purpose of large-area heat dissipation.

[0033] The aluminum plate component 2 is entirely made of aluminum plate. Since the bottom of the touch controller 102 of the purchased touchscreen 1 has a downward-protruding structure, an inwardly recessed air groove 204 is formed on the aluminum plate component 2 at the bottom wall of the touchscreen mounting groove 203 to ensure convenient installation. When the touch controller 102 heats up, some of the heat can be directly diffused into the space inside the air groove 204, and then absorbed and dissipated over a large area by the aluminum plate component 2 itself, thereby lowering the temperature inside the air groove 204. However, this conduction path is inefficient. The heat from the touchscreen 1 cannot be quickly dissipated, and traditional heat-conducting media such as thermal grease suffer from aging and maintenance issues. Therefore, a dense array of upward-protruding heat-conducting bumps 206 is formed within the air groove 204. After the touchscreen 1 is installed, the top plane of the heat-conducting bumps 206 forms a multi-node metal contact with the bottom of the touch controller 102. The dense multi-plane structure eliminates micro-gaps between the contact interfaces, allowing heat flow to be efficiently introduced into the aluminum plate component 2 through the heat-conducting bumps 206 without the need for a heat-conducting medium, achieving rapid heat conduction. Furthermore, the structure of the heat-conducting bumps 206 reduces the overall weight of the aluminum plate component 2, lowering maintenance costs. The addition of the heat-conducting bumps 206 effectively conducts heat from the touchscreen 1. Simultaneously, the air groove 204, together with the first wire hole 207 and the second wire hole 208, forms an air convection channel, driving the exchange of hot and cold air and further reducing the temperature of the touchscreen 1.

[0034] A further improvement is that the touch unit 101, the touch controller 102, and the air slot 204 are all square. The touch unit 101 is located directly above the touch component 102. When the touch screen 1 is installed in the touch screen mounting slot 203, the air slot 204 is located directly below the touch controller 102. The air slot 204 is provided with a plurality of heat-conducting bumps 206. The top of the heat-conducting bumps 206 is in contact with the bottom of the touch controller 102. A portion of the heat from the touch controller 102 diffuses into the air slot 204 and forms air convection exchange with the first wire hole 207 and the second wire hole 208. Another portion of the heat is directly conducted through the heat-conducting bumps 206 and diffused into the aluminum plate component 2, thereby uniformly conducting the heat from the touch controller 102 to the aluminum plate component 2 through the heat-conducting bumps 206, and then dissipating heat from the aluminum plate component 2.

[0035] The function of the heat-conducting bumps 206 is to conduct heat from the touch controller 102 in a highly dense and uniform multi-node manner. The heat generated at the bottom of the touch controller 102 is quickly conducted through the heat-conducting bumps 206 and then cooled down. The heat-conducting bumps 206 and the aluminum plate component 2 are integrally formed. When the temperature of the touch controller 102 rises, the heat is quickly conducted to the entire aluminum plate component 2 through the heat-conducting bumps 206, thereby making the heat evenly distributed and quickly dissipated through the body of the aluminum plate component 2.

[0036] Compared to traditional flat-plane contact for heat dissipation, the heat-conducting bumps 206 are arranged in a high-density array, and the top surface of the heat-conducting bumps 206 adopts a precision-milled flat structure, providing sufficient contact surface with the heat source. The integrated milled heat-conducting bumps 206 form a multi-point contact network, and the continuity between the heat-conducting bumps 206 and the base material of the aluminum plate component 2 enhances the heat conduction effect. The air grooves 204 increase airflow, ensuring that the temperature of the touch screen 1 can be controlled within the normal allowable temperature range.

[0037] Furthermore, the heat-conducting bumps 206 are square in structure and arranged in a high-density array. By having these arrayed heat-conducting bumps 206 directly contact different areas of the bottom of the touch controller 102, heat accumulation near the touch controller 102 can be avoided. Combined with the large-area aluminum plate component 2, it can absorb a large amount of heat and dissipate it to the environment more evenly and effectively across its entire surface. Simultaneously, since the sides and part of the back of the aluminum plate component 2 are exposed to the air, heat can be rapidly exchanged through contact with the air on the sides and part of the back of the aluminum plate component 2.

[0038] Furthermore, it also includes a joystick controller 3, a joystick control guide hole 201 on the touch screen 1 and the aluminum plate component 2 for the joystick controller 3 to pass through, the joystick controller 3 is fixed on the aluminum plate component 2 and its bottom passes through the rectangular frame 40, the remote sensing control guide hole 201 plays a positioning role, so that the joystick controller 3 and the touch screen 1 are on the same vertical axis.

[0039] Furthermore, an LED circuit board mounting groove 202 is provided on the aluminum plate component 2 and located on the bottom wall of the touch screen mounting groove 203. An LED display board 7 is installed in the LED circuit board mounting groove 202. The LED display board 7 includes a fixing part 701 and an LED display part 702 that are perpendicularly arranged and are both elongated. The fixing part 701 is fixed to the bottom wall of the LED circuit board mounting groove 202 by screws. Multiple LED beads are installed on the LED display part 702 and spaced apart along the length of the LED display part. Light guide columns 8 are also installed on the LED display part at the LED beads. The bottom wall of the LED circuit board mounting groove 202 is also provided with wire holes through which wires for connecting the LED display board 7 and the control motherboard are passed. The addition of light guide columns makes the light from the LED display board refracted onto the touch screen evenly and softly, and improves the brightness of the light source, effectively reducing power consumption. Compared with traditional LED beads, LED beads only require less energy to produce bright light, thus improving luminous efficiency.

[0040] Furthermore, the LED circuit board mounting slot 202 includes a fixing slot 2021 and a mounting slot 2022 that respectively cooperate with the fixing part 701 and the LED display part 702. The lower part of the mounting slot 2022 is constructed as an elongated slot that cooperates with the LED display part 702, and the upper part is constructed as an upper light guide post fixing slot 205 that cooperates with each of the light guide posts 8. The fixing slot 2021 and the mounting slot 2022 facilitate the embedded installation of the fixing part 701 and the LED display part 702, thereby ensuring the accuracy of the installation position of the fixing part 701 and the LED display part 702. At the same time, with the help of the light guide post fixing slot 205, the installation and positioning of the light guide post 8 can be made more convenient.

[0041] Furthermore, a plurality of second screw holes 4011 for fixing the aluminum plate component 2 are evenly provided on the mounting plane 401. The second screw holes 4011 are used to fix the aluminum plate component 2 to the adapter frame component 4.

[0042] Furthermore, the bottom cover component 6 includes a bottom cover housing 60 with an open upper end. A plurality of first screw holes 4021 for connecting to the bottom cover housing 60 are evenly provided on the connecting piece 402. The connecting piece 402 is formed by bending the edge of the rectangular frame 40 downwards. This connection method effectively saves materials and space. Meanwhile, the bottom area of ​​the aluminum plate component 2 is larger than that of the bottom cover housing 60 and the mounting plane 401. Through the heat dissipation area of ​​the aluminum plate component 2 in contact with air, it can achieve the purpose of air cooling, thereby allowing the heat inside the aluminum plate component 2 to be quickly carried away by the external airflow.

[0043] Furthermore, the bottom cover housing 60 also includes a front end wall, a rear end wall, and two oppositely arranged side walls disposed on the lower bottom arm. The rear end wall is higher than the front end wall, and the side walls are constructed in the shape of a right trapezoid. This design makes the touch screen and the viewing angle close to a right angle, so that the user can see the content on the touch screen in both standing and sitting postures.

[0044] Furthermore, the control motherboard 5 is fixed to the mounting post 602 of the bottom cover with standard screws. The chip of the control motherboard 5 is located at the ventilation hole 601 of the bottom cover. The heat generated by the chip is dissipated by the air, thus achieving the purpose of heat dissipation without the need to add other components.

[0045] Furthermore, the bottom cover ventilation hole 601 includes multiple evenly arranged mesh holes in a rectangular array. Multiple fixing posts 602 are evenly distributed at the edge of the bottom cover ventilation hole 601. The fixing posts 602 are vertically upward so that a ventilation gap is formed between the control motherboard 5 and the mesh plate. The ventilation gap guides the cold air to flow along multiple sets of bottom cover ventilation holes 601, that is, to flow in a superimposed form in the horizontal and vertical directions, so as to carry away the heat of the chip.

[0046] Furthermore, a bottom cover protrusion 603 is provided on the outer side of the bottom wall of the bottom cover housing 60. The bottom cover protrusion 603 raises the plane of the bottom cover to allow cold air to enter the keyboard, which is the key to forming the interaction between cold and warm air.

[0047] Furthermore, a circular rubber sheet 9 is fitted on the bottom of the raised foot 603 of the bottom cover. The circular rubber sheet 9 is made of hard granular rubber, which increases the friction of the keyboard on the flat surface and plays a role in preventing slippage.

[0048] Furthermore, the bottom cover housing 60 is assembled from a steel plate with a thickness of 1.5mm. The purpose of this is to increase the weight and solve the problem of keyboard misalignment or displacement during use.

[0049] It is readily understood that those skilled in the art can combine, split, or reorganize the embodiments provided in this application to obtain other embodiments, all of which do not exceed the protection scope of this application.
