Description
Technical Field
[0001] This utility model relates to the field of keyboards, and in particular to a keyboard with an angle adjustment function. Background Technology
[0002] A keyboard is an input device that transmits user commands, text, symbols, and other data to electronic devices such as computers, mobile phones, and tablets via keystrokes. It is one of the core tools for human-computer interaction and is widely used in scenarios such as word processing, game control, programming, and data input. With the continuous advancement of technology, its technology is developing towards wireless, miniaturization, and multi-functionality.
[0003] Regarding the aforementioned technologies, the inventors discovered that due to differences in hand size and typing habits among different groups of people, prolonged use of the keyboard can lead to carpal tunnel syndrome, such as numbness, tingling, and weakness in the fingers. However, traditional keyboard designs often cannot flexibly adjust the tilt angle during use, which not only fails to meet the personalized needs of users but may also cause tension in the wrist and arm, increasing the risk of occupational musculoskeletal injuries. Utility Model Content
[0004] The main technical problem solved by this invention is to provide a keyboard with an angle adjustment function, which makes it easy to adjust the keyboard's usage angle, meet the user's personalized needs, and reduce the risk of occupational musculoskeletal injuries.
[0005] To solve the above technical problems, the present invention adopts the following technical solution: providing a keyboard with angle adjustment function, including: a keyboard body and a support base, a connecting seat is installed on one side of the bottom of the keyboard body, and a limit adjustment seat assembly is symmetrically connected to one side of the top of the support base. The limit adjustment seat assembly is rotatably connected to the connecting seat, and a buffer guide mechanism is symmetrically provided between the keyboard body and the support base.
[0006] The limiting adjustment seat assembly includes a mounting seat and an oblong opening on one side thereof. A limiting gear mounted on a connecting seat is rotatably connected inside the oblong opening. A mounting plate is connected to the side of the mounting seat near the oblong opening. A rotating rod is rotatably connected inside the oblong opening. An inclined limiting baffle is connected to one end of the rotating rod near the oblong opening, and the other end extends to the outside of the mounting seat and is connected to a drive plate. The assembly also includes an elastic element that drives the limiting baffle to move toward the limiting gear.
[0007] When the angle between the keyboard body and the support base increases, the limiting gear drives the limiting baffle to swing toward the elastic member.
[0008] By adopting the above technical solution, the keyboard body and the support base are connected by a rotating structure, allowing users to flexibly adjust the keyboard tilt angle according to their needs to accommodate different users' hand postures. When adjusting the tilt angle, the keyboard body drives the limiting gear to rotate. At this time, the keyboard body drives the limiting gear to rotate and causes the limiting baffle to swing towards the elastic element, ensuring the stability of the keyboard body when adjusting the angle. The elastic element ensures that the baffle and the gear are tightly engaged to prevent the angle from loosening. In addition, when the keyboard body angle is reset, by moving the drive plate, it is pressed against the elastic element, and the limiting gear and the limiting baffle are separated from each other, thus achieving automatic reset. During reset, the impact force during the adjustment process is absorbed by the buffer guide mechanism to avoid sudden angle changes affecting the user's operation.
[0009] In a preferred embodiment, the present invention can be further configured as follows: the buffer guide mechanism includes a clearance groove formed on the support base, sliding grooves are respectively formed on both sides of the clearance groove, a T-shaped slider is slidably connected between the sliding grooves, a damping telescopic rod assembly is installed in the clearance groove, one end of the damping telescopic rod assembly is connected to the T-shaped slider, and a hinge assembly is connected between the T-shaped slider and the keyboard body.
[0010] By adopting the above technical solution, the clearance groove provides installation space for the T-shaped slider and the damping telescopic rod assembly, allowing them to move within a certain range. The sliding groove constrains the movement direction of the T-shaped slider, ensuring that it can only slide along a predetermined path, preventing the T-shaped slider from deviating from its direction during the buffering process. This allows the linear motion of the damping telescopic rod assembly to be converted into the rotation of the hinge assembly, thereby driving the keyboard body to adjust its angle. In conjunction with the damping telescopic rod assembly, it provides a damping effect, buffering the impact force during the keyboard body angle adjustment process, making the adjustment process smoother.
[0011] In a preferred embodiment, the present invention can be further configured as follows: the damping telescopic rod assembly includes a sealing cylinder and a connecting plate connected to one end thereto; a guide rod is slidably passed through one end of the sealing cylinder; a rubber plug located in the inner cavity of the guide rod is connected to one end of the guide rod; and the other end is connected to a T-shaped slider; and at least one vent hole is opened at the end of the sealing cylinder away from the rubber plug.
[0012] By adopting the above technical solution, the sealing cylinder provides a sealed space for the reciprocating motion of the guide rod, ensuring the stable realization of the damping effect. The damping force is generated by the cooperation of the rubber plug and the guide rod, providing a buffer for the angle adjustment of the keyboard body. At the same time, the vent is used to balance the air pressure inside and outside the sealing cylinder, ensuring that the guide rod can move smoothly during the reciprocating motion, avoiding the obstruction of the guide rod movement due to air pressure changes inside the sealing cylinder, and ensuring the normal operation of the damping telescopic rod assembly.
[0013] In a preferred embodiment, the present invention can be further configured as follows: the hinge assembly includes a connecting rod, a hinge plate one symmetrically arranged at the bottom of the keyboard body, and a hinge plate two symmetrically arranged on the T-shaped slider. The two ends of the connecting rod are respectively connected to mounting sleeves, and the mounting sleeves are rotatably connected to the corresponding hinge plate one and hinge plate two respectively through pins.
[0014] By adopting the above technical solution, the connecting rod connects the keyboard body and the T-shaped slider, converting the linear motion of the T-shaped slider into the rotation of the keyboard body, thus realizing the conversion of motion form. Furthermore, through the action of hinge plate one, hinge plate two, mounting sleeve, and pin, the relative rotation between the connecting rod and the hinge plate is realized, allowing the buffering effect of the damping telescopic rod assembly to directly act on the angle adjustment process of the keyboard body, improving the flexibility and convenience of adjustment.
[0015] In a preferred embodiment, the present invention can be further configured as follows: an elastic protective component is symmetrically installed on the bottom side of the keyboard body away from the connector. The elastic protective component includes a mounting cylinder, a T-shaped rod is slidably inserted inside the mounting cylinder, a spring located inside the mounting cylinder is connected to the top of the T-shaped rod, a rubber hemispherical pad is connected to the bottom end of the T-shaped rod, and a hemispherical groove matching the rubber hemispherical pad is symmetrically opened on the top of the support base.
[0016] By adopting the above technical solution, the mounting cylinder provides a sealed space for the reciprocating motion of the T-shaped rod, ensuring the stable realization of the elastic force. When the keyboard body returns to the horizontal state, the pressure is transmitted to the spring through the movement of the T-shaped rod in the mounting cylinder to achieve buffering. In addition, the rubber hemispherical pad provides support and protection for the keyboard body, ensuring that the rubber hemispherical pad can be stably kept in the hemispherical groove when subjected to external force, thereby improving the stability and reliability of the elastic protection component.
[0017] In a preferred embodiment, the present invention can be further configured such that the elastic element is a conical spring.
[0018] By adopting the above technical solution, the conical spring has a structure that gradually becomes thinner or thicker. This design allows the spring to distribute pressure evenly when under force, avoiding local stress concentration.
[0019] In summary, this utility model includes at least one of the following beneficial technical effects of a keyboard with angle adjustment function:
[0020] 1. When adjusting the tilt angle, the keyboard body drives the limiting gear to rotate and causes the limiting baffle to swing towards the elastic element, ensuring the stability of the keyboard body when adjusting the angle. The elastic element ensures that the baffle and the gear are tightly engaged to prevent the angle from loosening. In addition, when the keyboard body angle is reset, the drive plate is moved to squeeze the elastic element and separate the limiting gear and the limiting baffle from each other, thus achieving automatic reset. This effectively reduces wrist and arm fatigue caused by long-term typing and significantly improves the comfort of use.
[0021] 2. Through the synergistic effect of the damping telescopic rod assembly, hinge assembly, and elastic protection assembly, the keyboard body tilt angle can be flexibly adjusted. The guide rod in the damping telescopic rod assembly slides inside the sealed cylinder, and the damping effect is achieved through the rubber plug and vent hole, so that the keyboard rotates smoothly and steadily during the adjustment process. Users can easily adjust the tilt angle of the keyboard according to their personal habits and needs, so as to find the most suitable typing posture for themselves. Attached Figure Description

[0034] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0035] It should be noted that these figures are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.
[0036] Reference Figure 1-6This utility model discloses a keyboard with angle adjustment function, comprising: a keyboard body 1 and a support base 2. A connecting seat 3 is installed on one side of the bottom of the keyboard body 1. A limit adjustment seat assembly 40 is symmetrically connected to one side of the top of the support base 2. The limit adjustment seat assembly 40 is rotatably connected to the connecting seat 3. A buffer guide mechanism 50 is symmetrically provided between the keyboard body 1 and the support base 2. The buffer guide mechanism 50 includes a clearance groove 51 formed on the support base 2. Sliding grooves 52 are respectively formed on both sides of the clearance groove 51. The sliding grooves 52 slide between each other. A T-shaped slider 53 is dynamically connected, and a damping telescopic rod assembly 54 is installed in the clearance groove 51. One end of the damping telescopic rod assembly 54 is connected to the T-shaped slider 53. A hinge assembly 55 connects the T-shaped slider 53 and the keyboard body 1. The limit adjustment seat assembly 40 includes a mounting seat 41 and an oblong opening 42 on one side thereon. A limit gear 43 mounted on the connecting seat 3 is rotatably connected in the oblong opening 42. A mounting plate 44 is connected to the side of the mounting seat 41 near the oblong opening 42. A rotating rod 45 is rotatably connected in the oblong opening 42. The rotating rod 45 is located near the oblong opening 42. One end of the opening 42 is connected to an inclined limiting baffle 46, and the other end extends to the outside of the mounting base 41 and is connected to a drive plate 47. It also includes an elastic element 48 that drives the limiting baffle 46 to move towards the limiting gear 43. When the angle between the keyboard body 1 and the support base 2 increases, the limiting gear 43 drives the limiting baffle 46 to swing towards the elastic element 48, which is a conical spring. When the keyboard body 1 adjusts the tilt angle, it drives the limiting gear 43 to rotate. At this time, the keyboard body 1 drives the limiting gear 43 to rotate, and the limiting baffle 46 moves towards the elastic element 47. The 8-swing mechanism ensures the stability of the keyboard body 1 when adjusting its angle, while the elastic element 48 ensures that the limiting baffle 46 and the limiting gear 43 are tightly engaged, preventing the angle from loosening and providing support for the keyboard body 1 after angle adjustment. In addition, when the keyboard body 1 is reset, the drive plate 47 is moved to squeeze the elastic element 48 and separate the limiting gear 43 and the limiting baffle 46, thus achieving automatic reset. During reset, the buffer guide mechanism 50 absorbs the impact force during the adjustment process, avoiding sudden angle changes from affecting the user's operation.
[0037] The damping telescopic rod assembly 54 includes a sealing cylinder 541 and a connecting plate 542 connected to one end thereon. A guide rod 543 is slidably passed through one end of the sealing cylinder 541. One end of the guide rod 543 is connected to a rubber plug 544 located in its inner cavity, and the other end is connected to a T-shaped slider 53. The end of the sealing cylinder 541 away from the rubber plug 544 has at least one vent hole 545. The hinge assembly 55 includes a connecting rod 551, a hinge plate 552 symmetrically arranged at the bottom of the keyboard body 1, and a hinge plate 553 symmetrically arranged on the T-shaped slider 53. The two ends of the connecting rod 551 are respectively connected to mounting sleeves 554. The mounting sleeves 554 are respectively connected to the corresponding hinge plate 552 and hinge plate 553 via pins. 53 Rotational connection; When the keyboard body 1 is reset at the angle, the connecting rod 551 converts the linear motion of the T-shaped slider 53 into the rotation of the keyboard body 1 through the action of the first hinge plate 552, the second hinge plate 553, the mounting sleeve 554, and the pin. At the same time, the T-shaped slider 53 drives the guide rod 543 to move, so that the rubber plug 544 generates damping force in the sealing cylinder 541, providing a buffer for the angle adjustment of the keyboard body 1. Meanwhile, the vent 545 is used to balance the air pressure inside and outside the sealing cylinder 541, ensuring that the guide rod 543 can move smoothly during the reciprocating motion, avoiding the obstruction of the movement of the guide rod 543 due to changes in air pressure inside the sealing cylinder 541, and ensuring the normal operation of the damping telescopic rod assembly 54.
[0038] Elastic protective components 60 are symmetrically installed on the bottom side of the keyboard body 1 away from the connecting seat 3. The elastic protective components 60 include a mounting cylinder 61, a T-shaped rod 62 that slides through the mounting cylinder 61, a spring 63 located inside the mounting cylinder 61 connected to the top of the T-shaped rod 62, and a rubber hemispherical pad 64 connected to the bottom end of the T-shaped rod 62. The top of the support base 2 is symmetrically provided with hemispherical grooves 7 that match the rubber hemispherical pad 64. When the angle of the keyboard body 1 is about to return to its original position, the rubber hemispherical pad 64 is subjected to the force buffered by the damping telescopic rod assembly 54 and is placed in the hemispherical groove 7. At this time, the T-shaped rod 62 transmits the pressure to the spring 63 to achieve buffering, and together with the rubber hemispherical pad 64, it provides support and protection for the keyboard body 1, ensuring that the rubber hemispherical pad 64 can be stably kept in the hemispherical groove 7 when subjected to external force, thereby improving the stability and reliability of the elastic protective components 60.
[0039] The implementation principle of this embodiment is as follows: During use, the user turns the keyboard body 1 counterclockwise, causing the keyboard body 1 to rotate the limiting gear 43 and the limiting baffle 46 to swing towards the elastic member 48. When a suitable angle is determined, the elastic member 48 drives the limiting baffle 46 to mesh tightly with the limiting gear 43 through its own elasticity to form a limiting mechanism, preventing the angle from loosening and providing support force after the keyboard body 1 is adjusted to meet the user's personalized needs. After use, when returning to the horizontal angle, the drive plate 47 is moved to make the limiting baffle 46 press against the elastic member 48. At this time, the limiting baffle 46 and the limiting gear 43 separate from each other, allowing the keyboard body 1 to rotate toward the support base 2. At this time, the hinge assembly 55 drives the T-shaped slider 53 to drive the guide rod 543 to move, causing the rubber plug 544 to generate damping force in the sealing cylinder 541, providing a buffer for the angle adjustment of the keyboard body 1. Meanwhile, the vent 545 balances the air pressure inside and outside the sealing cylinder 541, ensuring that the guide rod 543 can move smoothly during reciprocating motion, and preventing the guide rod 543 from being obstructed due to changes in air pressure inside the sealing cylinder 541, so as to ensure the normal operation of the damping telescopic rod assembly 54.
