[0001] The utility model relates to the technical field of computer keyboards, in particular to a split computer keyboard with adjustable angles. Background Art

[0002] With the continuous advancement of computer technology, keyboards, as a core device for human-computer interaction, are constantly being innovated and optimized. Traditional keyboard designs are often fixed or integrated. While they can meet basic input needs, their limitations are becoming apparent in certain work environments and application scenarios. Therefore, it is necessary to design a new keyboard that can both meet users' personalized needs and improve their work efficiency.

[0003] For example, the patent specification of an existing Chinese patent (publication number: CN109947263A) discloses a split-type computer keyboard with adjustable angle, including a keyboard body; the keyboard body includes a left control area and a right control area of ​​the keyboard, the upper contact points of the left control area and the right control area of ​​the keyboard are rotatably connected by a pin shaft, and the lower contact points of the left control area and the right control area of ​​the keyboard are provided with a fixing component for fixing, and also include an arc-shaped limit plate fixed to the side of the lower end of the left control area of ​​the keyboard away from the pin shaft, and the arc-shaped limit plate is provided with an arc-shaped groove, and the arc-shaped groove is slidably connected to a columnar fixing block fixed on the right control area of ​​the keyboard.

[0004] However, in the implementation of related technologies, it was found that the above-mentioned split-type computer keyboard with adjustable angle has the following problems: although the angle between the two areas of the keyboard can be adjusted during use, the adjustment range is limited and cannot truly adapt to the specific needs of different users, and has certain limitations.

[0005] In view of this, a split-type computer keyboard with adjustable angle is provided to overcome the above-mentioned drawbacks. Utility Model Content

By setting the mounting block and the mounting groove, and the mounting block and the foot pad are made of the same material, the user can easily insert the softer mounting block into the mounting groove to fix the foot pad. Similarly, when the foot pad needs to be removed and replaced with a higher base pad, the foot pad can be directly pushed from one side with force to pull the mounting block out of the mounting groove. These settings enable the device to easily complete the replacement of the foot pad.

[0011] As a further description of the above technical solution: a plurality of annular grooves are opened inside the sub-keyboard, a limiting column is fixedly installed inside the annular groove, a sliding sleeve is slidably mounted on the outer wall of the limiting column, and a protrusion is fixedly installed on the top of the sliding sleeve.

[0012] As a further description of the above technical solution: a plurality of through grooves are opened through the outer wall of the slide, and the spacing between the plurality of through grooves is the same as the spacing between the plurality of protrusions. By setting the spacing between the plurality of through grooves to be the same as the spacing between the plurality of protrusions, the plurality of through grooves and the protrusions can be adapted to each other at the same time.

[0013] As a further description of the above technical solution: a movable groove is provided on the side wall of the sub-keyboard, and the movable groove is interconnected with multiple annular grooves. A connecting rod is fixedly connected to the outer walls of multiple sliding sleeves at the same time, and a push block is fixedly connected to one side of the connecting rod. The connecting rod can be slid inside the annular groove. By setting the connecting rod and setting the connecting rod to fix multiple sliding sleeves at the same time, the user can drive the multiple sliding sleeves to move by moving the connecting rod, making the movement of multiple sliding sleeves easier.

[0014] As a further description of the above technical solution: a return spring is fixedly connected to the bottom end of the sliding sleeve, and the other end of the return spring is fixedly connected to the inner wall of the annular groove.

[0015] The utility model has the following beneficial effects:

[0027] Example 1

[0028] Reference Figure 1-7 The utility model provides a split computer keyboard with adjustable angle: it includes a main keyboard 1 and a sub-keyboard 2, a fixing component for connecting the main keyboard 1 and the sub-keyboard 2, the fixing component including: a clamping block 7 fixedly installed on one side of the main keyboard 1, a clamping slot 8 fixedly installed on the sub-keyboard 2 close to the main keyboard 1, and limit slots 4 are installed at the upper and lower ends of the main keyboard 1 and the sub-keyboard 2 at the same time. A slidable slide 5 is provided inside the limit slot 4, a square block is installed on the top of the main keyboard 1, and a protective cover 3 is hinged on the top of the square block. The area of ​​the protective cover 3 is larger than the main keyboard 1. By providing the protective cover 3, the user can use the protective cover 3 to protect the keys on the surface of the sub-keyboard 2 and the main keyboard 1 inside, preventing the keys from being damaged and preventing dust from accumulating on the surfaces of the sub-keyboard 2 and the main keyboard 1. Four foot pads 17 are installed at the bottom of the main keyboard 1, and the specific material of the foot pad 17 is rubber. Four foot pads 17 are also installed at the bottom of the sub-keyboard 2. By setting four foot pads 17 at the bottom of the sub-keyboard 2 and the main keyboard 1, the sub-keyboard 2 and the main keyboard 1 can remain stable when used separately, and the material of the foot pads 17 is rubber, which is non-slip, so that the sub-keyboard 2 and the main keyboard 1 will not be easily moved without human power, and can be used more stably. The bottom of the main keyboard 1 and the sub-keyboard 2 are provided with mounting grooves 19, and the bottom end of the foot pads 17 is integrally formed with a mounting block 18, which is adapted to the mounting groove 19. By setting the mounting block 18 and the mounting groove 19, and the mounting block 18 and the foot pads 17 are made of the same material, the user can easily insert the relatively soft mounting block 18 into the mounting groove 19, thereby fixing the foot pad 17. Similarly, when it is necessary to remove the foot pad 17 and replace it with a higher bottom pad, the foot pad 17 can be directly pushed from one side to pull the mounting block 18 out of the mounting groove 19. These settings enable the device to easily complete the replacement of the foot pad 17.

[0029] During specific implementation, when the user needs to use the entire keyboard, the slide 5 can be slid so that the slide 5 is on one side of the auxiliary keyboard 2 and the main keyboard 1. The slide 5 is limited by the limit groove 4 installed at the edge of the auxiliary keyboard 2 and the main keyboard 1 to prevent the slide 5 from separating from the keyboard body. After the slide 5 is on one side of the auxiliary keyboard 2 and the main keyboard 1 at the same time, the auxiliary keyboard 2 and the main keyboard 1 cannot move up and down. Because the auxiliary keyboard 2 and the main keyboard 1 are clamped together by the clamping block 7 and the clamping groove 8, the clamping block 7 and the clamping groove 8 cannot be separated after the auxiliary keyboard 2 and the main keyboard 1 cannot move up and down. These settings can clamp the main keyboard 1 and the auxiliary keyboard 2 when the user does not need to use the main keyboard 1 and the auxiliary keyboard 2 separately, so that the keyboard can be used normally.

[0030] When the main keyboard 1 and the auxiliary keyboard 2 need to be used separately, the slide 5 only needs to be completely slid to one side of the main keyboard 1, and then the auxiliary keyboard 2 can be pushed downward to separate the main keyboard 1 and the auxiliary keyboard 2.

[0031] By setting up fixed components, users can easily complete the splicing and separation of the main keyboard 1 and the auxiliary keyboard 2, so that users can determine the placement and angle of the main keyboard 1 and the auxiliary keyboard 2 according to their own habits or comfort level, which can fully meet the usage needs of different users.

[0032] In addition, the main keyboard 1 and the sub-keyboard 2 are each separately provided with a Bluetooth module and a power supply module, so that the main keyboard 1 and the sub-keyboard 2 can be used normally after being separated. The Bluetooth module and the power supply module are both existing technologies and will not be elaborated here.

[0033] Example 2

[0034] Reference Figure 1-7 The utility model provides a split computer keyboard with adjustable angle: a plurality of annular grooves 10 are provided inside the auxiliary keyboard 2, a limiting column 11 is fixedly installed inside the annular groove 10, a sliding sleeve 12 is slidably provided on the outer wall of the limiting column 11, a protrusion 16 is fixedly installed on the top of the sliding sleeve 12, a plurality of through-slots 6 are provided on the outer wall of the slide 5, and the spacing between the plurality of through-slots 6 is the same as the spacing between the plurality of protrusions 16. By setting the spacing between the plurality of through-slots 6 to be the same as the spacing between the plurality of protrusions 16, the plurality of through-slots 6 and the protrusions 16 can be adapted to the same time. There is a movable groove 15, which is interconnected with multiple annular grooves 10. A connecting rod 14 is fixedly connected to the outer walls of multiple sliding sleeves 12 at the same time. A push block 9 is fixedly connected to one side of the connecting rod 14. The connecting rod 14 is slidable inside the annular groove 10. By setting the connecting rod 14 and setting the connecting rod 14 to fix multiple sliding sleeves 12 at the same time, the user can drive the multiple sliding sleeves 12 to move by moving the connecting rod 14, making the movement of multiple sliding sleeves 12 easier. The bottom end of the sub-keyboard 2 is fixedly connected to a reset spring 13, and the other end of the reset spring 13 is fixedly connected to the inner wall of the annular groove 10.

[0035] During specific implementation, based on the above-mentioned embodiment 1, generally after the user moves the slide 5, because the slide 5 is slidable inside the limit groove 4, the slide 5 may be affected by external force and move, thereby causing problems in the connection between the main keyboard 1 and the sub-keyboard 2. In this use, the slide 5 will press the multiple protrusions 16 downward during the movement, so that the protrusions 16 retract into the annular groove 10, until the slide 5 is fully moved into place, the multiple protrusions 16 coincide with the center points of the multiple through grooves 6, and the protrusions 16 automatically reset by relying on the elastic force of the reset spring 13 to limit the slide 5, making it difficult for the slide 5 to be moved without human power, so that the user can use the keyboard in the combined state with confidence.

[0036] By setting the through groove 6 and the protrusion 16 to match each other, connecting the connecting rod 14 to the rear end of the protrusion 16, and connecting the return spring 13 between the connecting rod 14 and the inner wall of the annular groove 10, the protrusion 16 can limit the slide 5, making it difficult for the slide 5 to be moved without human power, thereby increasing the stability of the keyboard.

[0037] In addition, if you feel it is more laborious to push the slide 5, you can push the push block 9 in advance so that the push block 9 drives the connecting rod 14 to move multiple sliding sleeves 12 into the annular groove 10 at the same time. At this time, you can easily push the slide 5 by applying force.

[0038] Working principle:

[0039] When using the present invention, the slide 5 can be slid so that the slide 5 is on one side of the auxiliary keyboard 2 and the main keyboard 1. The slide 5 is limited by the limit grooves 4 installed at the edges of the auxiliary keyboard 2 and the main keyboard 1 to prevent the slide 5 from separating from the keyboard body. After the slide 5 is on one side of the auxiliary keyboard 2 and the main keyboard 1 at the same time, the auxiliary keyboard 2 and the main keyboard 1 cannot move up and down. Because the auxiliary keyboard 2 and the main keyboard 1 are clamped together by the clamping block 7 and the clamping groove 8, the clamping block 7 and the clamping groove 8 cannot be separated after the auxiliary keyboard 2 and the main keyboard 1 cannot move up and down. These settings can clamp the main keyboard 1 and the auxiliary keyboard 2 when the user does not need to use the main keyboard 1 and the auxiliary keyboard 2 separately, so that the keyboards can be used normally.

[0040] When the main keyboard 1 and the auxiliary keyboard 2 need to be used separately, the slide 5 only needs to be completely slid to one side of the main keyboard 1, and then the auxiliary keyboard 2 can be pushed downward to separate the main keyboard 1 and the auxiliary keyboard 2.

[0041] By setting up fixed components, users can easily complete the splicing and separation of the main keyboard 1 and the auxiliary keyboard 2, so that users can determine the placement and angle of the main keyboard 1 and the auxiliary keyboard 2 according to their own habits or comfort level, which can fully meet the usage needs of different users.

[0042] Generally, after the user moves the slide 5, because the slide 5 is slidable inside the limit groove 4, the slide 5 may be affected by external force and move, thereby causing problems in the connection between the main keyboard 1 and the sub-keyboard 2. In this use, the slide 5 will press the multiple protrusions 16 downward during the movement, so that the protrusions 16 retract into the annular groove 10, until the slide 5 is fully moved into place, the multiple protrusions 16 coincide with the center points of the multiple through grooves 6, and the protrusions 16 automatically reset by the elastic force of the reset spring 13 to limit the slide 5, making it difficult for the slide 5 to be moved without human power, so that the user can use the keyboard in the combined state with confidence.

[0043] By setting the through groove 6 and the protrusion 16 to match each other, connecting the connecting rod 14 to the rear end of the protrusion 16, and connecting the return spring 13 between the connecting rod 14 and the inner wall of the annular groove 10, the protrusion 16 can limit the slide 5, making it difficult for the slide 5 to be moved without human power, thereby increasing the stability of the keyboard.

[0044] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
