Description

Technical Field

[0001] This invention relates to the field of mouse technology, and more specifically, to a laptop computer. Background Technology

[0002] Laptops, with their lightweight and portable features, have become essential tools for daily office work. Although laptops have touchpads that can be used as mice, they are far less comfortable and efficient than a mouse, so people often carry a separate mouse with their laptops. When out and about, it's common to forget to bring a mouse, leaving only the touchpad as a last resort, which is inconvenient. While there are existing technologies that allow the touchpad to be detached from the laptop and used as a mouse, the height of the detached touchpad is often unsuitable for individual needs. Summary of the Invention

[0003] The main objective of this invention is to provide a laptop computer that solves the problem that the height of the touchpad is difficult to meet individual differences when used as a mouse after being removed from the existing technology.

[0004] To achieve the above objectives, the present invention provides a laptop computer, comprising: a computer body; a touchpad detachably mounted on the computer body; the touchpad including a button section and a touch panel, the touch panel being connected to one side of the button section; the computer body and the touch panel being signal-connected to enable the touchpad to have a mounted state with sliding sensing function and a dismounted state without sliding sensing function; wherein, the button section includes a housing, the height of the housing relative to the desktop is adjustable; a lens is disposed within the housing, the lens having multiple mounting heights within the housing, the multiple mounting heights being adapted to different heights of the housing relative to the desktop.

[0005] In some embodiments, one side of the housing and one side of the touchpad are rotatably connected so that the height of the bottom of the housing from the desktop is adjustable.

[0006] In some embodiments, there are multiple lenses with different mounting heights, and the button area is configured to selectively use lenses that are adapted to the height of the housing relative to the tabletop.

[0007] In some embodiments, a light source is provided inside the housing, and multiple lenses are movably disposed below the light source so that one of the multiple lenses moves to the point where it is aligned with the light path emitted by the light source.

[0008] In some embodiments, the button portion further includes a driver, which is connected to the lens drive to enable the lens to have a use state that allows the light path of the light source to pass through and an avoidance state that prevents the light path of the light source from passing through.

[0009] In some embodiments, the touchpad further includes a height-adjustable riser disposed at the bottom of the housing to give the housing different heights.

[0010] In some embodiments, one end of the heightening member is rotatably connected to the bottom of the housing, and the other end of the heightening member is movably disposed so that the heightening member has a retracted state that fits against the bottom of the housing and a supported state that raises the housing.

[0011] In some embodiments, a lens is provided on the heightening member; when the heightening member is in a retracted state, the light path of the light source passes through the lens; when the heightening member is in a supported state, the light path of the light source avoids the lens.

[0012] In some embodiments, the touchpad is positioned away from the center line of the keyboard on the computer body.

[0013] In some embodiments, the computer body is provided with a signal transmitter, the touchpad is provided with a signal receiver, and the signal transmitter is connected to the signal receiver; and / or, the computer body is provided with a mounting slot, the side wall of the mounting slot is provided with a first magnetic attraction point, and the side of the touchpad is provided with a second magnetic attraction point corresponding to the first magnetic attraction point; and / or, the laptop computer also includes a heightening component, which may be optionally disposed at the bottom of the touchpad.

[0014] By applying the technical solution of this application, the laptop computer sets the touchpad as a detachable structure and establishes a signal connection between the touchpad and the computer body, realizing a dual working mode where the touchpad has a sliding sensing function when installed and loses this function when disassembled. This allows the touchpad to be used as a mouse when disassembled, solving the problem in the prior art that requires a separate mouse to be carried and used with the laptop, which brings inconvenience to daily office work.

[0015] When the touchpad is installed on the computer, it can be used as a standard laptop touchpad. When the user removes it, the component transforms into an independent physical structure without a sliding sensor, serving as a support for the palm and wrist. The touchpad's button section includes a housing with a pressing element on the top. Inside the housing are lenses, a light source, and a photoelectric sensor, enabling the touchpad to function as a mouse, thus overcoming the limitation of traditional touchpads that cannot operate independently of the host computer.

[0016] By incorporating an adjustable-height lens within the button housing, and allowing the lens to be installed at multiple heights within the housing, with each height matching different adjustment positions of the housing relative to the desktop, users can flexibly adjust the height of the housing relative to the desktop after disassembly, based on their hand shape, operating habits, or desktop height. Simultaneously, the lens automatically adapts to the corresponding installation height, ensuring precise alignment between the finger's pressing trajectory on the button surface and the lens's imaging area, guaranteeing tracking accuracy. This significantly improves control precision and comfort in disassembled states, resolving the issue of varying mouse height preferences among individuals. This design not only overcomes the limitations of existing technologies where the touchpad cannot be flexibly detached and used as an independent mouse, but also effectively overcomes the problem of varying mouse height preferences after disassembly through the installation height-lens linkage mechanism, achieving a seamless functional transformation from an integrated input device to an adaptive independent peripheral.

[0028] like Figures 1 to 5 As shown, the present invention provides a laptop computer, including: a computer body 100; a touchpad 200, the touchpad 200 being detachably mounted on the computer body 100; as shown Figure 2 As shown, the touchpad 200 includes a button section 210 and a touchpad 220, with the touchpad 220 connected to one side of the button section 210. The computer body 100 is signal-connected to the touchpad 220, enabling the touchpad 220 to have both an installed state with sliding sensing function and an uninstalled state without sliding sensing function. The button section 210 includes a housing 213, the height of which is adjustable relative to the desktop. A lens 211 is disposed within the housing 213, and the lens 211 has multiple mounting heights within the housing 213, each height adapting to different heights of the housing 213 relative to the desktop. Figure 3 As shown. More specifically, the button section 210 includes a press button, which is disposed on the upper part of the housing 213 and is used for pressing and clicking with a finger. The button section 210 also includes a photoelectric sensor 215. After passing through the lens 211, the light shines onto the table surface and is then reflected by the table surface. The reflected light enters the photoelectric sensor 215, such as... Figure 5 As shown.

[0029] Specifically, in order to ensure the tracking accuracy of the touchpad 200 when used as a mouse, the height of the lens 211 from the desktop needs to be within a preset range. Preferably, the lower end of the lens 211 is within a preset range of 0.2-0.25mm from the desktop.

[0030] After disassembling the device, users can increase the height of the housing 213 from the table according to their hand shape, operating habits, or table height. This will raise the lens 211 inside the housing 213. In order to ensure tracking accuracy, it is necessary to reduce the installation height of the lens 211 inside the housing 213 so that the height of the lens 211 from the table is within a preset range.

[0031] Applying the technical solution of this embodiment, the laptop computer includes a computer body 100 and a touchpad 200 detachably mounted thereon. The touchpad 200 consists of a button section 210 and a touchpad 220, with the touchpad 220 connected to one side of the button section 210. The computer body 100 establishes a signal connection with the touchpad 220, enabling the touchpad 220 to be in an installed state with sliding sensing function when mounted on the computer body 100, and in a dismounted state without sliding sensing function after being removed from the computer body 100. It also provides wrist support. Simultaneously, the button section 210 possesses the basic functions of a mouse, thereby enabling flexible function switching between the touchpad 200 as a built-in input device in the laptop computer and as a standalone peripheral mouse. This solves the problem in the prior art where the laptop touchpad 200 cannot be detached and used as an independent mouse. This invention addresses the problem of existing technologies requiring separate mouse and laptop use, which is inconvenient for daily office work. The button unit 210 includes a housing 213, which is height-adjustable relative to the desktop. Inside the housing 213 is a lens 211 with multiple preset installation heights. These installation heights correspond to different adjustable heights of the housing 213 relative to the desktop. When the user adjusts the height of the housing 213 according to ergonomic needs, the optical working position of the lens 211 automatically matches, ensuring that the optical tracking system is always in the optimal imaging and tracking height range when used as a standalone mouse. This effectively solves the technical defects of mouse positioning drift and decreased tracking accuracy caused by height mismatch, significantly improving the operational stability and accuracy in detached mode.

[0032] Furthermore, in this embodiment, one side of the housing 213 and one side of the touchpad 220 are rotatably connected so that the height of the bottom of the housing 213 from the desktop is adjustable.

[0033] In this embodiment, one side of the housing 213 and one side of the touchpad 220 are rotatably connected to each other, allowing for relative rotation and meeting the user's comfort requirements. When the housing 213 is adjusted around this connection point, the height of its bottom relative to the desktop changes linearly. Then, the lens 211 is adjusted to the corresponding installation height, ensuring that the lens 211 is always in its optimal working position and that the optical tracking accuracy is not affected by height deviation.

[0034] Furthermore, in this embodiment, there are multiple lenses 211 with different mounting heights, and the button part 210 is configured to selectively use lenses 211 that are adapted to the height of the housing 213 relative to the table.

[0035] In this embodiment, when the height of the housing 213 relative to the desktop is adjusted to different positions, the multiple lenses 211 provided in the button section 210 can be selectively activated according to the height state of the housing 213. Each lens 211 corresponds to a specific installation height within the housing 213, so that the optical working distance of the lens 211 is precisely matched with the actual height of the housing 213 from the desktop, thereby ensuring that the optical tracking system can maintain the best positioning accuracy and response stability at any height. Through this height-adaptive lens 211 selection mechanism, the tracking drift or sensitivity reduction problem caused by the working distance shift when the housing 213 is raised or lowered by a single fixed-height lens 211 is avoided, which significantly improves the control accuracy and user experience consistency of the touchpad 200 when used as an independent mouse after being detached from the computer body 100.

[0036] Furthermore, in this embodiment, a light source 212 is provided inside the housing 213, and multiple lenses 211 are movably disposed below the light source 212 so that one of the multiple lenses 211 can move to the light path emitted by the light source 212.

[0037] In this embodiment, when the height of the housing 213 relative to the desktop is adjusted, the multiple lenses 211 inside it can be movably configured so that one of the lenses 211 adapted to the current height of the housing 213 can be precisely moved to the center position of the light path emitted by the light source 212, thereby ensuring that the light from the light source 212 always forms an effective optical path through the corresponding lens 211, avoiding tracking errors caused by light path offset due to height changes; through this movable lens 211 matching mechanism, dynamic alignment of the light path and the lens 211 can be achieved at different installation heights, significantly improving the optical tracking accuracy and stability of the touchpad 200 when it is detached and used as an independent mouse, while maintaining structural compactness and ease of operation.

[0038] Furthermore, in this embodiment, the button part 210 also includes a driving member 214, which is drivenly connected to the lens 211 so that the lens 211 has a use state that allows the light path of the light source 212 to pass through and an avoidance state that prevents the light path of the light source 212 from passing through.

[0039] In this embodiment, when the height of the housing 213 of the button section 210 relative to the desktop is adjusted, the driving component 214 automatically drives the lens 211 to switch between a state where the light path of the light source 212 passes through and a state where the light path of the light source 212 is avoided, based on the current height position of the housing 213. This ensures that only the lens 211 adapted to the current height enters the light path of the light source 212, while the other lenses 211 are reliably avoided. This maintains the accurate alignment and effective transmission of the light path of the light source 212, avoiding light path interference or tracking deviation caused by the coexistence of multiple lenses 211, and significantly improving the positioning accuracy and operational consistency of the touchpad 200 under different height usage states. This driving mechanism achieves adaptive matching of the height of the lens 211 and the housing 213 through the linkage response of structure and height, so that the touchpad 200 can still maintain stable optical tracking performance when used as an independent mouse after disassembly.

[0040] Furthermore, in this embodiment, the touchpad 200 also includes a height-adjustable riser 230, which is disposed at the bottom of the housing 213 to allow the housing 213 to have different heights. Optionally, the height-adjustable riser 230 is a riser pad or a support leg structure.

[0041] In this embodiment, when the height-adjustable extension member 230 is set at the bottom of the housing 213, the extension length of the extension member 230 can be adjusted to achieve multiple height changes of the housing 213 relative to the desktop, thereby matching the natural hand-raising posture of different users when using it independently after disassembly. At the same time, the installation height of the multiple lenses 211 inside the housing 213 is synchronously adapted with the overall height adjustment of the housing 213, ensuring that the lenses 211 are always in the optimal optical imaging position, so that the touchpad 220 can still maintain accurate touch response and operation stability after being removed from the computer body 100. This structure, through the reliable support and height adjustment function provided by the extension member 230, solves the technical defects of the traditional touchpad 200, which has a fixed installation height and poor human-computer adaptability due to the lack of an adjustable support structure after disassembly, and significantly improves the comfort and practicality of using it as an independent mouse after disassembly.

[0042] Furthermore, in this embodiment, one end of the heightening member 230 is rotatably connected to the bottom of the housing 213, and the other end of the heightening member 230 is movably disposed so that the heightening member 230 has a retracted state that fits against the bottom of the housing 213 and a supported state that raises the housing 213.

[0043] In this embodiment, when one end of the heightening member 230 is rotatably connected to the bottom of the housing 213 and the other end is movably set, the heightening member 230 can flexibly switch between a retracted state and a supported state: in the retracted state, the heightening member 230 fits against the bottom of the housing 213, keeping the touchpad 200 at a low height for easy storage or close mounting to the laptop body 100; in the supported state, the heightening member 230 unfolds by rotation, with its movable end abutting against the desktop, thereby stably raising the housing 213 and achieving a relative height of the housing 213 to the desktop. The height adjustment precisely matches the multiple mounting heights of the lens 211 inside the housing 213, ensuring that the lens 211 is always in the optimal optical working position under different support heights, improving touch accuracy and response consistency. This structure does not require additional locking mechanisms or fasteners, and relies solely on rotation and gravity self-locking to achieve stability, which simplifies the structure and improves the ease of operation. At the same time, it avoids lens 211 imaging shift or sensing failure caused by sudden height changes, so that the touchpad 200 can still maintain high-precision sliding sensing performance when disassembled and used independently.

[0044] Furthermore, in this embodiment, a lens 211 is provided on the heightening member 230; when the heightening member 230 is in the retracted state, the light path of the light source 212 passes through the lens 211; when the heightening member 230 is in the supported state, the light path of the light source 212 avoids the lens 211.

[0045] In this embodiment, when the riser 230 is in the retracted state, the lens 211 on it forms an optical path connection with the light source 212 inside the housing 213, allowing the light emitted by the light source 212 to accurately pass through the lens 211 and be projected onto the touch surface, ensuring that the touchpad 200 has stable optical tracking capability in the installed state. When the riser 230 is flipped to the support state to raise the housing 213, the lens 211 is completely removed from the optical path range of the light source 212 due to the position shift, so that the light no longer passes through the lens 211, thereby avoiding tracking misjudgment or signal noise caused by interference of the optical path by the non-compatible lens 211 in the independent mouse use mode, significantly improving touch accuracy and operation stability. Through this structural linkage design, the automatic matching of the lens 211 and the riser 230 state is realized, and the intelligent switching of the optical path can be completed without additional detection or control circuits, which simplifies the system structure and enhances the seamless switching experience between the installed and disassembled modes of the device.

[0046] Furthermore, in this embodiment, the touchpad 200 is positioned away from the keyboard centerline of the computer body 100.

[0047] In this embodiment, the touchpad 200 is positioned away from the center line of the keyboard on the computer body 100. This allows the touchpad 220 and the keypad 210 to be offset to one side of the keyboard area when the computer is installed. This prevents the user's thumb or palm from accidentally touching the touchpad 220 area due to natural sliding when using the keyboard, effectively reducing the frequency of accidental triggering during operation. At the same time, since the touchpad 220 is connected to one side of the keypad 210, and the computer body 100 maintains a signal connection with the touchpad 220, this offset layout does not affect the normal transmission and response of the touch function. Instead, it optimizes the ergonomic path, allowing the user to naturally move their palm to the touchpad 200 away from the center line of the keyboard for precise operation while maintaining the keyboard input posture. This significantly reduces hand fatigue and discomfort caused by repetitive movements, improving the overall comfort and accuracy of the interaction.

[0048] Furthermore, in this embodiment, the computer body 100 is provided with a signal transmitter, and the touchpad 220 is provided with a signal receiver, the signal transmitter and the signal receiver being connected; and / or, the computer body 100 is provided with a mounting slot, the side wall of the mounting slot is provided with a first magnetic attraction point, and the side of the touchpad 200 is provided with a second magnetic attraction point 240 corresponding to the first magnetic attraction point, such as... Figure 4 As shown; and / or, the laptop also includes a riser 230, which may be optionally positioned at the bottom of the touchpad 220.

[0049] In this embodiment, a signal transmitter is provided inside the computer body 100, and a signal receiver is provided inside the touchpad 220. The signal transmitter and the signal receiver are connected, so that the touchpad 200 can still maintain communication with the computer body 100 via wireless signal transmission after being removed from the computer body 100. This allows the touchpad 220 to switch between an installed state with precise sliding sensing function and a disassembled state without sliding sensing function. At the same time, the computer body 100 is provided with a mounting slot, and the side wall of the mounting slot is provided with a first magnetic attraction point. The side of the touchpad 200 is provided with a second magnetic attraction point 240 corresponding to the first magnetic attraction point, and the touchpad 200 is positioned by magnetic attraction. The touchpad 200 and the computer body 100 are quickly, stably, and without mechanical plug-in loss through detachable assembly, avoiding poor contact or structural damage caused by loose plugging or misalignment. In addition, the laptop also includes a height-adjusting component 230, which can be selectively set at the bottom of the touchpad 220 to raise the height of the touchpad 220. This allows the touchpad 220 to flexibly adapt to different working heights according to the user's hand shape, usage posture, or desktop environment when used independently. This overcomes the technical limitations of relying solely on the housing 213 itself, which has a limited adjustment range and cannot meet diverse usage needs, and significantly improves ergonomics and user comfort.

[0050] The process of the technical solution in this application is described below:

[0051] When the touchpad 200 is installed on the computer body 100, the touchpad 220 is signal connected to the computer body 100 and is in the installation state with the sliding sensing function. At this time, the bottom of the housing 213 is in contact with the surface of the computer body 100, and the riser 230 is in the retracted state and in contact with the bottom of the housing 213. At this time, the touchpad 220 has the sliding sensing function.

[0052] When the user needs to remove the touchpad 200 from the computer body 100 for use as an independent mouse, the touchpad 200 is removed from the mounting slot of the computer body 100. At this time, the touchpad 220 is disconnected from the signal connection and enters a disassembled state without the sliding sensing function. Subsequently, the user flips the riser 230 from the retracted state to the supported state. One end of the riser 230 is unfolded by a rotating connection, and the other end abuts against the desktop, thereby raising the height of the housing 213 relative to the desktop. The lens 211 on the housing 213 moves to the bottom of the housing 213 with the riser 230 and is in a position to avoid the passage of light. At this time, the light emitted by the light source 212 forms an effective light path through the lens 211 inside the housing 213.

[0053] By applying the technical solution of this application, the laptop computer sets the touchpad 200 as a detachable structure and establishes a signal connection between the touchpad 220 and the computer body 100, realizing a dual working mode in which the touchpad 220 has a sliding sensing function when installed and loses this function when disassembled. This allows the touchpad 200 to be used as a mouse when disassembled, solving the problem in the prior art that requires a separate mouse to be carried and used with the laptop, which brings inconvenience to daily office work.

[0054] When the touchpad 200 is installed on the computer body 100, its touchpad 220 can be used as a standard notebook touchpad; when the user removes it, the component becomes an independent physical structure without the function of sliding sensing, and is used as a component to support the palm and wrist. The button part of the touchpad 200 includes a housing 213, and a press button is set on the top of the housing 213. The housing 213 contains a lens 211, a light source 212 and a photoelectric sensor 215, which enables the touchpad to have the function of a mouse, breaking through the limitation of traditional touchpads that cannot be operated independently without the host.

[0055] By incorporating an adjustable-height lens 211 within the housing 213 of the button section 210, and ensuring that the lens 211 has multiple mounting heights within the housing 213, each matching a different adjustment position of the housing 213 relative to the desktop, users can flexibly adjust the height of the housing relative to the desktop after disassembly, based on their hand shape, operating habits, or desktop height. Simultaneously, the lens position automatically adapts to the corresponding mounting height, ensuring tracking accuracy and significantly improving control precision and comfort in disassembled states. This design not only overcomes the limitation of existing technologies where touchpads cannot be flexibly detached and used as independent mice, but also effectively overcomes the control inaccuracy problem caused by mismatched mounting heights after disassembly through the mounting height-lens linkage mechanism, achieving a seamless functional transformation from an integrated input device to an adaptive independent peripheral.
