Description

[Technical field]

[0001] The invention belongs to the technical field of keyboard assembly, and in particular relates to a keyboard balance bar assembly clamping mechanism. [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 side ends, and both side ends are provided with hook parts; 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 the keyboard, it is very difficult to install the balance bar. It needs to be tilted at a very small angle, or even horizontally, and then inserted obliquely into the hole groove on the bottom plate / aluminum plate. The clamping mechanism used for assembling the balance bar in the prior art often causes the balance bar to fall off or be assembled unsmoothly, resulting in low balance bar assembly efficiency and low yield.

[0006] Therefore, it is necessary to provide a new keyboard balance bar assembly clamping mechanism 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 absorption and assembly of the balance bar, and greatly improve the assembly efficiency and assembly quality of the balance bar.

[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 seat, a driving member arranged on the mounting seat, a pair of magnetic suction members arranged on the mounting seat and movable up and down, a transmission module that converts the up and down driving action of the driving member into the up and down movement of the magnetic suction member, and a balance bar pushing plate driven by the transmission module to insert the balance bar along the assembly direction, and the two magnetic suction members are located on both sides of the balance bar pushing plate.

[0009] Furthermore, the transmission module includes a first connecting plate having one end hinged on the mounting seat through a first support shaft, a second connecting plate hinged to the other end of the first connecting plate through a first pin shaft, and a third connecting plate hinged on the mounting seat in the middle and hinged to the free end of the second connecting plate at one end, and the first connecting plate is driven by the driving member to swing around the first support shaft.

[0010] Furthermore, the middle portion of the balance bar push plate is hinged on the mounting seat via a third support shaft, and the bottom end of the balance bar push plate pushes the balance bar into the mounting hole slot by swinging around the third support shaft.

[0011] Furthermore, a guiding inclined groove penetrating through the left and right side surfaces is provided at the upper end of the balance bar pushing plate, and the first pin shaft passes through the guiding inclined groove.

[0012] Furthermore, the magnetic attraction component includes a mounting block and a magnet embedded in the mounting block.

[0013] Furthermore, the mounting seat is provided with a pair of vertically penetrating limiting holes, and the magnetic attraction member is movably arranged in the limiting holes up and down.

[0014] Furthermore, a limiting groove is provided on one side of the mounting block, and one end of the third connecting plate is inserted into the limiting groove.

[0015] Furthermore, the driving member is an electromagnet.

[0016] Furthermore, a receiving groove is provided in the mounting seat, and the transmission module and the balance bar pushing plate are both arranged in the receiving groove.

[0017] Furthermore, a pair of limiting grooves corresponding to and limiting the hook portion of the balance bar are provided on the lower surface of the mounting seat.

[0018] Compared with the prior art, the beneficial effects of the keyboard balance bar assembly clamping mechanism of the present invention are: the overall structure is small and reasonable, the structure is compact, and the space occupancy is small, which is more conducive to the configuration of multiple balance bar assembly clamping mechanisms with different specifications, and the assembly of multiple balance bars can be realized at the same time, thereby improving the assembly efficiency; the balance bar is absorbed by the magnetic attraction, and the up and down telescopic movement of the electromagnet is utilized, and the transmission module is cleverly designed to cooperate, so as to drive the magnetic attraction part to move up and down to realize automatic separation from the balance bar, effectively preventing the magnetic attraction from hindering the assembly of the balance bar, and avoiding the balance bar being stuck out again after assembly; the transmission module is also used to realize the swinging movement of the balance bar push plate, so that the horizontal push of the balance bar is realized in a narrow space, thereby ensuring the precise assembly of the balance bar, and greatly improving the assembly efficiency and assembly quality of the balance bar.

The first connecting plate 6 is driven by the driving member 2 to swing around the first supporting shaft 5. The second connecting plate 8 and the third connecting plate 9 are hinged together through a second pin shaft 10. The middle part of the third connecting plate 9 is rotatably arranged on the mounting seat 1 through a second supporting shaft 11.

[0028] The middle part of the balance bar push plate 4 is rotatably hinged on the mounting base 1 through the third support shaft 12. The upper end of the balance bar push plate 4 is provided with a guide inclined groove 41 penetrating the left and right surfaces, and the first pin shaft 7 passes through the guide inclined groove 41; the bottom end of the balance bar push plate 4 pushes the balance bar into the mounting hole groove by swinging around the third support shaft 12.

[0029] Two magnetic parts 3 are provided and located on both sides of the third connecting plate 5, which are used to absorb the two corners of the balance pole respectively. The magnetic part 3 includes a mounting block 31 and a magnet 32 ​​embedded in the mounting block 31. A pair of vertically through-going limiting holes 13 are provided on the mounting seat 1, and the magnetic part 3 is movably arranged in the limiting holes 13 up and down. A limiting groove 311 is provided on one side of the mounting block 31, and one end of the third connecting plate 9 is inserted into the limiting groove 311. When the third connecting plate 9 swings around the second support shaft 11, one end thereof drives the mounting block 31 to move up and down in the limiting hole 13.

[0030] A bracket 14 is provided on the mounting seat 1, and a driving member 2 is mounted on the bracket 14. The driving member 2 is an electromagnet or a linear cylinder.

[0031] A limit plate 15 is also provided on the mounting seat 1 to limit the upper limit height of the movement of the first pin shaft 7 .

[0032] The lower surface of the mounting seat 1 is provided with a pair of limiting grooves 16 corresponding to and limiting the bent hook portion of the balance pole.

[0033] A receiving groove 17 is provided in the mounting base 1, and the transmission module and the balance bar push plate 4 are both arranged in the receiving groove 17, which greatly reduces the volume of the overall structure and reduces the space occupied, making it more conducive to the configuration of the assembly clamping mechanism of multiple balance bars of different specifications, and realizing the assembly of multiple balance bars at the same time, thereby improving the assembly efficiency.

[0034] The working principle of the keyboard balance bar assembly clamping mechanism 100 in this embodiment is as follows: first, the magnetic suction member 3 adsorbs the two corners of the balance bar, and uses the two limit slots 16 to limit the two hook parts of the balance bar, so as to achieve precise adsorption of the balance bar. At this time, the end edge of the balance bar push plate 4 abuts against the straight bar section of the balance bar; after completing the absorption action of the balance bar, the balance bar clamping mechanism 100 as a whole can be moved to the keycap position to be installed through the transfer module. At this time, the bottom of the mounting block 1 is close to the surface of the keyboard bottom plate, and the end of the hook part of the balance bar is directly opposite to the installation jack slot; then the driving member 2 is started, and the telescopic rod of the driving member 2 extends downward. , driving the first connecting plate 6 to rotate downward around the first pin shaft 7, and under the transmission of the second connecting plate 8, pressing down one end of the third connecting plate 9, so that the other end of the third connecting plate 9 is lifted upward around the second support shaft 11, thereby driving the mounting block 31 to lift upward, disengaging from the balance pole and losing the adsorption effect on the balance pole. At the same time, under the cooperation of the first pin shaft 7 and the guide inclined groove 41 at the top of the balance pole pushing plate 4, the first pin shaft 7 pushes the top of the balance pole pushing plate 4 outward, so that the other end of the balance pole pushing plate 4 swings inward around the third support shaft 12, pushing the balance pole into the mounting hole groove along the guiding direction of the limit slot 16, and completing the assembly of the balance pole.

[0035] The present embodiment is a keyboard balance bar assembly clamping mechanism 100, which has a compact overall structure and utilizes magnetic attraction to absorb the balance bar. The up and down telescopic movement of the electromagnet is utilized, and a cleverly designed transmission module is used to cooperate, so as to drive the magnetic attraction component to move up and down to achieve automatic separation from the balance bar, thereby effectively preventing the magnetic attraction from hindering the assembly of the balance bar and avoiding the balance bar being stuck out again after assembly. The transmission module is also used to realize the swinging movement of the balance bar push plate, thereby realizing horizontal push of the balance bar in a narrow space, ensuring the precise assembly of the balance bar, and greatly improving the assembly efficiency and quality of the balance bar.
