[0023] Referring to Figures 1-7 The balance shaft structure of the mechanical keyboard large key comprises a balance shaft body A, the balance shaft body A is clamped in a large key installation position B1 of a keyboard panel B, and a tapered clamping position 12 is arranged on a shaft seat support 10 of the balance shaft body A.
[0024] The tapered clamping position 12 and the shaft seat support 10 are integrally formed, the upper end surface of the tapered clamping position 12 is designed to be downwardly inclined a, the inner side of the lower end surface is designed to be a plane b, and the outer side is designed to be upwardly inclined c; the inside of the shaft seat support 10 is hollow and is an inner shaft installation position 15, two elastic columns 11 vertically and in parallel and in consistent height are arranged at the front end and the rear end of the shaft seat support 10, and the tapered clamping position 12 protrudes in the middle of each elastic column 11; a front clamping groove 111 is arranged below the tapered clamping position 12 of the two elastic columns 11 at the front end of the shaft seat support 10; an elastic strip 14 is arranged in the middle of the two elastic columns 11 at the rear end of the shaft seat support 10, a protruding limiting protrusion 141 is arranged below the elastic strip 14, and a rear clamping groove 142 is formed between the tapered clamping position 12 and the limiting protrusion 141; the balance shaft body A is assembled in the large key installation position B1 of the keyboard panel B, the front end edge of the large key installation position B1 is located in the front clamping groove 111 below the elastic column 11 at the front end of the shaft seat support 10, the rear end edge of the large key installation position B1 is located in the rear clamping groove 142 at the rear end of the shaft seat support 10, and the elastic columns 11 arranged at the front end and the rear end of the shaft seat support 10 are clamped with the edges of the large key installation position B1 due to elasticity.
[0025] As a preferred scheme, the balance shaft body A comprises two shaft seat supports 10, two inner shafts 20 and a balance rod 30; the two inner shafts 20 are respectively located in the inner shaft installation positions 15 of the two shaft seat supports 10, and the two shaft seat supports 10 are respectively located at the two ends of the balance rod 30.
[0026] As a preferred scheme, a cross pattern is arranged on the upper end of the inner shaft 20 and is connected with a cross groove column arranged on the inner wall of the large key; the lower end of the inner shaft 20 is hollow.
[0027] As a preferred embodiment, the bottom front end of the bearing support 10 is provided with a forward-extending fixed baffle 13, the crossbar of the balance bar 30 is locked between the fixed baffle 13 and the bearing support 10, and the end of the balance bar 30 is locked into the hollow position inside the inner shaft 20.
[0028] The key design feature of this invention is that a protruding conical locking position is provided at the middle position of the elastic column at both ends of the bearing support. The upper end face of the conical locking position is designed to be inclined downwards, and the lower end face is designed to have a flat inner side and an upward-inclined outer side.
[0029] During installation: The keyboard panel is placed face down on the workbench, and the balance shaft body is placed face up on the other side of the workbench. The robotic arm grasps the bottom of the two balance shaft support brackets and inserts the balance shaft body from the back of the large key position. When the tapered locking post on the elastic post of the support bracket passes the edge of the large key position, the inclined surface of the tapered locking post compresses the elastic post inward under force, allowing the tapered locking post of the support bracket to pass through the large key position. The front edge of the large key position enters the front groove of the elastic post, and the rear edge of the large key position is located in the rear groove of the back of the support bracket. The elastic post recovers its elasticity and locks tightly with the front and rear edges of the large key position, ensuring a stable installation of the balance shaft body. After installation, with the keyboard panel face up, the tapered locking posts of the elastic posts of the support bracket are all above the large key position, the limiting protrusion at the lower end of the elastic bar is below the large key position, and the upper end of the elastic bar protrudes above the large key position.
[0030] If the balance shaft of the keyboard is damaged during use, the user needs to replace it.
[0031] When removing the damaged balance switch: Place the keyboard face up, remove the keycaps to expose the entire balance switch, press the elastic strip of one of the switch holders inward, and the limiting protrusion at the lower end of the elastic strip will disengage from the edge of the large key mounting position, so that the switch holder at this end separates from the edge of the large key mounting position. After this end is removed from the large key mounting position, the other end will also separate from the large key mounting position at the same time. Use the same operation to remove the other switch holder of the balance switch body, and then the balance switch can be removed as a whole.
[0032] When installing it themselves, just like in the background technology, first insert one side of the balance shaft at an angle into the large button mounting position, and then insert the other side into the large button mounting position to lock it in place.
[0033] This invention is reasonably designed and easy to install. The shaft support and tapered clamp are integrally formed by mold, and the process is simple. The simple design solves the huge problem of the industry's inability to achieve automated assembly line operation, bringing great economic efficiency to enterprises. It is worth promoting and using.
[0034] The above description is merely a preferred embodiment of the present invention, and the specific embodiments described above are not intended to limit the present invention. Various modifications and variations can be made within the scope of the technical concept of the present invention. All refinements, modifications, or equivalent substitutions made by those skilled in the art based on the above description are within the scope of protection of the present invention.
