Description

[Technical field]

[0001] The invention belongs to the technical field of keyboard balance bar assembly, and in particular relates to a keyboard balance bar assembly clamping mechanism and an assembly method. [Background technology]

[0002] In terms of current personal computer usage habits, the keyboard is one of the indispensable input devices for inputting text, symbols or numbers. In addition, all consumer electronic products in daily life or large-scale processing equipment used in the industrial sector need to be equipped with a key structure as an input device to operate the above electronic products and processing equipment.

[0003] Generally speaking, most of the keys on a keyboard device have square keycaps. A small number of keys, such as the space key, the enter key, the caps lock key, the shift key, etc., have keycaps that are longer than they are wide. These keys are called multiple keys. Since the key surface of multiple keys is longer, when typing on the keyboard, the user's fingers cannot guarantee that they will hit the middle of the keycap every time. If they hit the side, they need to apply greater pressure to the keycap to trigger the key effect. Therefore, a balance bar is needed to prevent the keycap from tilting or rising due to the difference in force points. The two ends of the keycap achieve a balanced effect, and the user can trigger the key by hitting any position of the keycap.

[0004] The balance bar in the existing keyboard is formed by bending a straight bar with a circular cross-section, the middle straight bar part is the balance part, and the two sides of the balance part are bent parts. Some balance bars are also provided with a hook part at the end of the bent part; the balance part of the balance bar is installed on the cover cap, and the bottom plate / aluminum plate is provided with a hole groove for inserting the hook part of the balance bar.

[0005] When assembling a keyboard, it is very difficult to install a balance bar with a hook. In the prior art, the balance bar is generally tilted at a very small angle, or even horizontally, and then the hook is relatively stretched and inserted into the hole groove on the bottom plate / aluminum plate. Since the installation space is very narrow, the balance bar clamping mechanism needs to occupy a certain space. Therefore, the assembly of the balance bar is particularly inconvenient. The clamping mechanism used for assembling the balance bar in the prior art often causes the balance bar to fall off or the assembly is not smooth, resulting in low assembly efficiency and low yield of the balance bar. In addition, the overall structure of the balance bar clamping and stretching structure is complex, and the space occupied is large, which is not conducive to operation in a small space, and the assembly efficiency is low and the qualified rate is poor.

[0006] Therefore, it is necessary to provide a new keyboard balance bar assembly clamping mechanism and assembly method to solve the above technical problems. [Summary of the invention]

[0007] The main purpose of the present invention is to provide a keyboard balance bar assembly clamping mechanism, which can effectively complete the clamping assembly of the balance bar in a small space without the need for a spreading action, and has high assembly efficiency and high assembly quality.

[0008] The present invention achieves the above-mentioned purpose through the following technical scheme: a keyboard balance bar assembly clamping mechanism, which includes a mounting plate, a first driving member fixed on the mounting plate, a first movable plate driven by the first driving member to move up and down on the mounting plate, a mounting base fixed to the bottom of the first movable plate, and a balance bar clamping block having one end hinged on the mounting base and located below the mounting base, and the other end of the balance bar clamping block is hung on the mounting base through an elastic member.

[0009] Furthermore, an axle seat is provided on the upper surface of the balance bar clamp, and one end of the balance bar clamp is rotatably mounted on the mounting seat via a first pin shaft passing through the axle seat.

[0010] Furthermore, a limiting groove for limiting the rod-shaped portion of the balance pole is disposed on the lower surface of the balance pole clamping block, and a clamping plate for clamping the rod-shaped portion of the balance pole in the limiting groove is disposed inside.

[0011] Furthermore, the clamping plate is rotatably arranged in a limiting slot hole of the balance bar clamp through a second pin shaft, and a clamping spring is arranged in the limiting slot hole. The clamping spring supports the clamping plate so that it cooperates with the inner wall surface of the limiting groove to clamp the rod-shaped part of the balance bar.

[0012] Furthermore, an end limiting block for limiting one end of the rod-shaped portion of the balance bar is provided at one end of the limiting groove.

[0013] Furthermore, it also includes a second driving member, a second movable plate driven by the second driving member to move in the X-axis, a third driving member fixed on the second movable plate, and a third movable plate driven by the third driving member to move in the Y-axis, and the mounting plate is fixed on the third movable plate.

[0014] The present invention also provides an assembling method of a keyboard balance bar, which comprises the following steps:

[0015] S1) clamping the rod-shaped portion of the balance pole and making the rod-shaped portion in an inclined state, with two bent portions of the balance pole facing downward, with the hook portion at one end being low and the hook portion at the other end being high;

[0016] S2) clamping the balance bar in the above state and moving it to above the mounting hole slot seat, wherein the end of the hook portion at the lower end does not interfere with the corresponding mounting hole slot seat in the up and down direction;

[0017] S3) Clamp the balance bar and move it downward so that the end of the hook portion at the lower end is aligned with the hole slot on the corresponding mounting hole slot seat;

[0019] S5) continuously pressing down the balance bar so that the bar-shaped portion tends to be horizontal, and pressing the hook portion on the high end side into the hole groove of the corresponding mounting hole groove seat;

[0020] S6) Pull the balance bar back horizontally to the center position to complete the assembly.

[0021] Compared with the prior art, the beneficial effects of the keyboard balance bar assembly clamping mechanism and assembly method of the present invention are: providing a new balance bar assembly method, during the whole assembly process, the bent portion in the balance bar is kept in a vertical state, and the rod-shaped portion is tilted so that one side is high and the other side is low, and then the bent hook portion on the low side is horizontally moved and inserted into the hole groove of the bottom plate or the aluminum plate from the outside, and then the rod-shaped portion of the balance bar is flattened so that the bent hook portion on the high side of the other end is squeezed into the corresponding hole groove, thereby completing the assembly; by using a balance bar clamp block with an inclined clamping state and a horizontal clamping state, the assembly of the balance bar can be completed without the need to expand the balance bar, which greatly simplifies the structure of the balance bar clamping assembly module on the one hand, and simplifies the balance bar assembly action on the other hand, thereby improving the assembly efficiency.
