[0033] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0034] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0035] In the present disclosure, unless otherwise stated, the directional words used, such as "inside" and "outside", refer to the inside and outside relative to the outline of the component or structure itself. In addition, it should be noted that the terms used, such as "first" and "second", etc., are used to distinguish one element from another element and do not have order and importance. In addition, in the description with reference to the drawings, the same mark in different drawings represents the same element.

[0036] In order to achieve the above-mentioned purpose, the utility model discloses, on the one hand, a keyboard structure, which is suitable for being installed on a shell 1 of a laptop computer, and the shell 1 has an installation opening adapted to the shape of the keyboard structure, and the keyboard structure includes: a keyboard support structure 3, and the keyboard support structure 3 is provided with an air inlet 31; at least one lifting and lowering device 4, and the lifting and lowering device 4 is connected between the shell 1 and the keyboard support structure 3, and is used to lift or lower the keyboard support structure 3.

[0037] In order to ensure that the laptop computer has both lightness and heat dissipation performance, so that the laptop computer can better adapt to light, medium and heavy load states. Therefore, an air inlet 31 is set on the keyboard support structure 3 of the laptop keyboard 2, so that the wind can enter the space enclosed by the keyboard 2 and the shell 1 through the air inlet 31, take away the heat, and prevent the temperature of the laptop keyboard 2 and the shell 1 surface from being too high. Since the laptop keyboard is not always in a state where an additional air inlet 31 is required, and since the laptop computer has different states such as light, medium and heavy loads, the size and number of air inlets required are also different. In this case, a lifting and lowering device 4 is set between the laptop shell 1 and the keyboard support structure 3, and the lifting and lowering device 4 is used to drive the keyboard support structure 3 to rise or fall, so as to meet the requirements of the number and size of the air inlet 31 that need to be exposed when the laptop computer is in a light, medium and heavy load state.

[0038] Through the above technical solution, an air inlet hole 31 is set on the keyboard support structure 3 of the laptop computer, and the keyboard support structure 3 is raised to a corresponding height according to the load of the laptop computer by using the lifting and lowering device 4, so that air can be introduced into the keyboard 2 through the air inlet hole 31 of the keyboard support structure 3 to ensure the suitability of the surface temperature of the laptop computer keyboard 2 and the shell 1.

[0039] In one embodiment, Figure 3 As shown, the keyboard structure also includes: a keyboard 2, which is arranged on a keyboard support structure 3.

[0040] The heat source of the keyboard 2 and the housing 1 is mainly the heat radiation and heat conduction of the heat source components installed on the surface of the PCB (printed circuit board). Due to the demand for thin and light laptops in the market, the space in the laptop system is limited, which leads to the heat source on the PCB being closer to the keyboard 2 and the housing 1. This will make it easier for the keyboard 2 and the housing 1 to radiate heat. Excessive heat radiation will prevent the housing 1 from naturally dissipating heat, resulting in high-temperature hot spots on the surface of the keyboard 2 and the housing 1. The hot spots on the keyboard 2 and the housing 1 will make the user feel very hot when touching and use, making it impossible to continue using.

[0041] In order to solve the above problem, the keyboard 2 can be arranged on the keyboard support structure 3. In this way, as the lifting device 4 raises the keyboard support structure 3, the keyboard 2 will also rise. As the keyboard 2 rises, the distance between the keyboard 2 and the PCB will also increase. In this way, the space inside the computer system is increased and the heat dissipation is enhanced.

[0042] In one embodiment, the lifting and lowering device 4 is configured to determine the lifting height according to the load of the laptop computer.

[0043] The lifting and lowering device 4 can be an automatic lifting and lowering device, which uses an automatic lifting and lowering mechanical device to lift the keyboard bracket structure 3 of the air outlet 31 to different heights according to light, medium and heavy loads. In this way, airflow will pass through the shell 1 and the keyboard 2 ends, and the keyboard 2 and the shell 1 will also have forced convection instead of relying solely on natural convection as before. In addition, the notebook computer fan 5 will also add additional air intake at the keyboard 2 end, which will enhance the heat convection efficiency in the notebook computer system. The increase in the distance between the keyboard and the heat source also weakens the heat radiation of the heat source to it, and ultimately reduces the temperature of the keyboard 2, the shell 1 and the heat source chip. When the laptop computer is in a heavy load usage scenario, the heat generation of the heating components in the system increases. At this time, the fixed automatic lifting and lowering device uses the micromotor pulse signal on the automatic lifting and lowering device to drive the screw reducer to rotate in coordination according to the feedback of the temperature monitoring to adjust the degree of freedom, and lift the laptop keyboard to the highest position, so that the keyboard structure of the air outlet can be filled with air through the keyboard 2 on all sides. When the laptop computer is used in medium or light load scenarios, the automatic lifting and lowering mechanism will also maintain the keyboard structure of the air inlet hole in a proper position due to its force, so as to ensure the suitability of the surface temperature of the laptop computer keyboard 2 and the shell 1.

[0044] In one embodiment, Figure 6As shown, the lifting and lowering device 4 includes: a servo motor 41; a motor fixing frame 42, which is installed on the housing 1 and is used to fix the servo motor 41 on the motor fixing frame 42; a servo motor reducer, which is located inside the servo motor 41 and is used to convert the high-speed rotation of the servo motor 41 into a low-speed and high-torque rotation; a transmission part, which is driven by the servo motor 41 to move; and a lifting rod 43, which is in contact with the transmission part at one end and in contact with the keyboard 2 at the other end. The lifting rod 43 drives the keyboard 2 to rise or fall as the transmission part moves.

[0045] The working principle of the servo motor 41 is to first send speed and position instructions through the controller. After the position controller receives the instructions, it measures the rotation angle and speed of the output shaft through the encoder and feeds the data back to the position controller. The position controller controls the speed and position of the motor according to the data of the encoder. Then, the driver receives the control signal sent by the position controller and transmits the current to the motor to control the rotation of the motor. The servo motor 41 is fixed on the housing 1 through the motor fixing frame 42. The servo motor 41 can convert the voltage signal into torque and speed to drive the control object. In order to convert the high-speed rotation of the servo motor 41 into the low-speed and high-torque rotation of the output shaft, a servo motor reducer (not shown in the figure) is installed inside the servo motor 41. As the servo motor 41 rotates, the transmission part is driven to move, and the transmission part drives the lifting rod 43 to move up and down. As the lifting rod 43 moves up and down, the keyboard 2 is driven to rise or fall. A spring can also be set on the lifting rod 43, so that a buffering force can be given to the keyboard 2 when the lifting rod 43 drives the keyboard 2 to rise or fall.

[0046] In one embodiment, Figure 6 As shown, the transmission component includes: a screw rod 44 , which is connected to the servo motor 41 ; and a screw rod nut 45 , which is sleeved on the screw rod 44 and contacts the lifting rod 43 .

[0047] The transmission part drives the lifting rod 43 to move as the servo motor 41 rotates. The servo motor 41 drives the screw rod 44 to rotate forward and reverse along the axis of the screw rod through the screw rod 44 connected thereto. A screw nut 45 is also sleeved on the screw rod 44. The screw nut 45 moves in the horizontal direction along the screw rod 44 as the screw rod 44 rotates. As the screw nut 45 moves, the lifting rod 43 also rises or falls accordingly.

[0048] like Figure 7-Figure 9 As shown in FIG. 1 , the operating principle of the lifting and landing device 4 is shown. The initial state of the lifting and landing device 4 is as follows: Figure 7As shown in FIG. 1 , the servo motor 41 is not running, and the screw nut 45 is close to the motor. As the servo motor 41 rotates, the screw 44 is driven to rotate, and the screw nut 45 sleeved on the screw 44 also moves to the right, driving the lifting rod 43 to move in the vertical direction, that is, to move upward. The rising state is shown in FIG. Figure 8 As the servo motor 41 continues to operate, the screw rod 44 drives the screw nut 45 to continue to move to the right, and the lifting rod 43 also continues to move upward until Fig. 9 The status is stopped.

[0049] In one embodiment, Figure 6-9 As shown, the contact surface between the screw nut 45 and the lifting rod 43 is a wedge-shaped surface.

[0050] The wedge-shaped structure mainly has the two characteristics of being able to change the direction of the applied force and being compact. In order to save space, the contact surface between the screw nut 45 and the lifting rod 43 is designed as a wedge-shaped surface, so that the direction of the applied force of the screw nut 45 can be changed. As the screw nut 45 moves in the horizontal direction, the wedge-shaped surface changes the horizontal force into a vertical force, so the lifting rod 43 moves in the vertical direction under the action of the force that changes the direction.

[0051] In one embodiment, Figure 6-9 As shown, the contact surface between the lifting rod 43 and the screw nut 45 is a wedge-shaped surface.

[0052] The wedge structure has two main characteristics: it can change the direction of the force and has a compact structure. In order to save space, the contact surface between the lifting rod 43 and the screw nut 45 is designed as a wedge surface, so that the force direction of the lifting rod 43 can be changed. As the screw nut 45 moves in the horizontal direction, the wedge surface changes the horizontal force into a vertical force, so the lifting rod 43 moves in the vertical direction under the action of the force that changes the direction.

[0053] The contact surfaces of the lifting rod 43 and the screw nut 45 can be either a wedge-shaped surface or both of them can be wedge-shaped surfaces, which is not limited here.

[0054] In one embodiment, Figure 6 As shown, the lifting and lowering device 4 also includes a motor reduction base 46 , and the motor reduction base 46 is sleeved on the lifting rod 43 .

[0055] In one embodiment, Figure 6 As shown, a magnet 47 is provided on the side of the motor reduction base 46 facing the keyboard 2 .

[0056] As the servo motor 41 rotates in reverse, the screw nut 45 moves leftward under the action of the screw 44 , the lifting rod 43 descends, and the laptop computer keyboard 2 is brought to an initial equilibrium state by the action of the screw and the magnet 47 .

[0057] In one embodiment, Figure 2 As shown, the keyboard support structure 3 has at least one buckle 32, and the buckle 32 is connected to the mounting opening of the housing 1 for limiting the keyboard support structure 3 in the horizontal direction.

[0058] When the keyboard support structure 3 is raised to different heights, the buckle 32 beside the keyboard support structure 3 is connected to the installation opening of the housing 1 to ensure the horizontal stability of the keyboard support structure 3, and to fix the shape of the keyboard 2 in time to ensure that the keyboard 2 can work normally. There can be multiple buckles 32, and the specific number is not limited, as long as it meets the technical requirements and safety requirements.

[0059] In one embodiment, Figure 5 As shown, the air inlet hole 31 is at least one fence-type strip hole.

[0060] The fence-type strip holes can better utilize the area of ​​the keyboard support structure 3 and can better prevent dust. The fence-type strip holes of the air inlet 31 are only one embodiment, and the air inlet 31 can also be a hexagon, a small round hole, a strip pill hole, etc. It only needs to meet the appearance requirements and safety requirements, and there is no limitation here.

[0061] In one embodiment, Figure 4 As shown, the keyboard 2 has at least one hole, and the hole is used to increase the heat dissipation area of ​​the keyboard 2.

[0062] For further heat dissipation, on the basis of adding air inlet holes 31 on the keyboard support structure 3, circular holes can also be provided on the keyboard 2 to increase the heat dissipation area of ​​the keyboard 2 and better play the heat dissipation function of the keyboard structure.

[0063] On the other hand, the present invention provides a notebook computer housing 1 , wherein the housing 1 is provided with an installation opening adapted to the shape of a keyboard structure.

[0064] The last aspect of the present invention provides a laptop computer, characterized in that the laptop computer comprises the keyboard structure in the aforementioned embodiment and the shell of the laptop computer in the aforementioned embodiment.
