Description

Technical Field

[0001] This utility model relates to the field of keyboards, and more particularly to a spring damping and buffering structure for keyboards. Background Technology

[0002] Keyboards, as essential input devices for computers and other electronic devices, are widely used in daily life and work. As users' demands for keyboard experience continue to rise, comfort, quiet operation, and durability have become crucial design considerations.

[0003] Traditional keyboard key structures typically use simple elastic elements (such as rubber pads or springs) to achieve the key reset function. However, this structure is prone to elastic fatigue after prolonged use, resulting in a deterioration in key feel. The elasticity of the damping pads is limited, and they are prone to deformation after long-term use, leading to a decrease in damping effect. Furthermore, key presses can easily generate noise and vibration, affecting the user experience. Based on these considerations, we propose a spring-based vibration damping and buffering structure for keyboards. Utility Model Content

[0004] To address the technical problem of elastic fatigue in keyboard key structures, this invention provides a spring-loaded damping and buffering structure for keyboards.

[0005] This utility model is achieved by the following technical solution: a spring damping and buffering structure for a keyboard, including keyboard keys, a buffering mechanism installed below the keyboard keys, and a shock-absorbing mechanism connected below the buffering mechanism.

[0006] The buffer mechanism includes a receiving seat, a buffer spring connected to the bottom of the receiving seat, the bottom end of the buffer spring connected to a mounting plate, and a connecting seat installed below the mounting plate.

[0007] The shock absorption mechanism includes:

[0008] A connecting post is installed below the connecting seat, and a damper is connected to the bottom of the connecting post;

[0009] The return spring, the top of the return spring, and the bottom of the return spring are connected to the upper end of the damper, which is connected to the bottom end of the connecting post.

[0010] Connecting block, the connecting block is installed on the outside of the connecting post;

[0011] The reset rod has its top end connected to the connecting block, and its bottom end connected to a sliding shaft. The sliding shaft is slidably connected inside a sliding groove, which is formed on the surface of the support frame. The sliding shaft engages within the sliding groove, and the reset rod pushes the bottom sliding shaft to slide within the groove.

[0012] As the button is pressed down, the buffer spring presses down on the connecting seat, which in turn presses down on the shock-absorbing mechanism connected to it. The connecting column then presses down, which in turn presses down on the reset spring. The connecting block presses down simultaneously, and the connecting block presses down on the reset rod connected to it. The reset rod drives the sliding shaft to slide in the sliding groove, further dispersing and reducing vibration and noise when the button is pressed, ensuring smooth button reset.

[0013] As a further optimization of this utility model, when the user presses a keyboard key, the buffer mechanism under the key first absorbs part of the impact force through a buffer spring.

[0014] As a further optimization of this utility model, the receiving seat is connected to the bottom of the keyboard keys. One or two sets of receiving seats are provided. Two sets of receiving seats are installed under the long strip-shaped keyboard keys; one set of receiving seats is installed under the smaller keys of the keyboard, such as the letter keys and number keys.

[0015] As a further optimization of this utility model, the high elasticity design of the reset spring and the buffer spring ensures that the keyboard keys can still maintain a good feel and vibration reduction effect after long-term use.

[0016] As a further optimization of this utility model, the support frame is a three-legged structure, and the support frame is connected and supported by three sets of reset rods.

[0017] As a further optimization of this utility model, the bottom end of the receiving seat extends downward with electronic contacts, and the inside of the connecting seat is provided with a circuit board. When the electronic contacts extending downward from the receiving seat are pressed, they contact the circuit board inside the connecting seat to realize the circuit connection and input of the keyboard.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] 1. When a user presses a keyboard key, the buffer mechanism beneath the key first absorbs part of the impact force through a buffer spring. The high elasticity design of the return spring and buffer spring ensures that the keyboard keys maintain good tactile feedback and vibration damping effect even after prolonged use.

[0020] 2. In this utility model, the connecting column presses down on the reset spring, and the connecting block presses down simultaneously. The connecting block presses down on the reset rod connected to it, and the reset rod drives the sliding shaft to slide in the sliding groove, which further disperses and reduces the vibration and noise when the button is pressed, ensuring the smooth reset of the button.

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0028] Example 1:

[0029] Please combine Figures 1-4 This embodiment proposes a spring damping and buffering structure for a keyboard, including a keyboard key 2 and a buffering mechanism 3 installed below the keyboard key 2, with a shock-absorbing mechanism 4 connected below the buffering mechanism 3.

[0030] The buffer mechanism 3 includes a receiving seat 31, a buffer spring 32 connected to the lower part of the receiving seat 31, the bottom end of the buffer spring 32 connected to the mounting plate 33, and a connecting seat 34 installed below the mounting plate 33.

[0031] Specifically, when the user presses the keyboard key 2, the buffer mechanism 3 below the key first absorbs part of the impact force through the buffer spring 32.

[0032] It should be noted that the receiving seat 31 is connected to the bottom of the keyboard key 2. There are one or two sets of receiving seats 31. Two sets of receiving seats 31 are installed under the long strip keyboard key 2; one set of receiving seats 31 is installed under the smaller keys of the letter keys and number keys of the keyboard key 2.

[0033] It should be noted that the bottom end of the receiving base 31 extends downward with an electronic contact 35, and the inside of the connecting base 34 is equipped with a circuit board. When the electronic contact 35 extending downward from the receiving base 31 is pressed, it contacts the circuit board inside the connecting base 34 to realize the circuit input of the keyboard.

[0034] Among them, the shock absorption mechanism 4 includes:

[0035] Connecting post 41 is installed below connecting seat 34, and damper 48 is connected to the bottom of connecting post 41;

[0036] The top of the return spring 42 is connected to the bottom of the connecting post 41, and the bottom of the return spring 42 is connected to the upper end of the damper 48.

[0037] Connecting block 43 is installed on the outside of connecting post 41;

[0038] The reset rod 44 has its top end connected to the connecting block 43, and its bottom end connected to a sliding shaft 45. The sliding shaft 45 is inserted into the interior of the sliding groove 46, which is formed on the surface of the support frame 47.

[0039] More specifically, with continuous downward pressure, the buffer spring 32 presses downward against the connecting seat 34, which in turn presses downward against the connected shock-absorbing mechanism 4. The connecting post 41 then presses downward against the return spring 42. Simultaneously, the connecting block 43 presses downward against the connected reset rod 44. The reset rod 44 drives the sliding shaft 45 to slide within the sliding groove 46, further dispersing and reducing vibration and noise when the key is pressed, ensuring smooth key reset. The high elasticity design of the return spring 42 and the buffer spring 32 ensures that the keyboard key 2 maintains good tactile feedback and vibration damping even after prolonged use.

[0040] The sliding shaft 45 is slidably connected inside the sliding groove 46, and the reset rod 44 pushes the bottom sliding shaft 45 to slide within the sliding groove 46.

[0041] Furthermore, the support frame 47 is a tripod structure, installed on the keyboard base plate 1, and the support frame 47 is connected and supported by three sets of reset rods 44.

[0042] Specific implementation steps of this utility model:

[0043] When the user presses keyboard key 2, the buffer mechanism 3 below the key first absorbs part of the impact force through the buffer spring 32. With continued downward pressure, the buffer spring 32 presses down on the connecting seat 34, which in turn presses down on the connected shock-absorbing mechanism 4. The connecting post 41 then presses down, pressing down on the return spring 42. Simultaneously, the connecting block 43 presses down, pressing down on the connected reset rod 44. The reset rod 44 drives the sliding axis 45 to slide within the sliding groove 46, further dispersing and reducing vibration and noise when the key is pressed, ensuring smooth key reset. The high elasticity design of the return spring 42 and the buffer spring 32 ensures that keyboard key 2 maintains good feel and vibration damping even after prolonged use.
