Description

A keyboard tray

Technical Field

The present application relates to a keyboard tray in the technical field of trays.

Background technique

As an important computer external device, the keyboard generally needs to reserve a certain space on the desktop to place it. However, the keyboard itself occupies a large area. In some scenarios where the desktop space is limited, many users will use a keyboard tray to place the keyboard.

Keyboard trays are divided into integrated and assembled types. An integrated keyboard tray means that the computer desk itself is equipped with a movable keyboard tray. A sliding rail is installed at the bottom of the desktop. The keyboard tray body slides out from under the desktop through the rail, and the keyboard is placed on the keyboard tray body. An assembled keyboard tray means that the computer desk itself is not designed with a corresponding keyboard tray. The keyboard tray is a structure that is assembled later, so the desk itself does not have bolt holes reserved for connecting with the keyboard tray. In this regard, the assembled keyboard trays on the market are generally fixed to the bottom of the desktop by clamping, and the keyboard tray body is also slid out by sliding rails.

However, as consumers have an increasing demand for personalized adjustments, they hope that the pitch angle of the keyboard can be adjusted according to the consumer's usage habits, so as to reduce the discomfort of the wrist during long-term use. Since the pitch adjustment range of the keyboard itself is limited, it is necessary to add a keyboard angle adjustment function to the keyboard tray. Although there are keyboard trays with added angle adjustment mechanisms on the market, the angle is fixed by tightening the knob, which is not stable and may fail when the user presses the keyboard frequently, causing the keyboard angle to change.

As consumers have an increasing demand for personalized adjustments, they hope that the pitch angle of the keyboard can be adjusted according to their usage habits, thereby reducing the discomfort of the wrist during long-term use. Since the pitch adjustment range of the keyboard itself is limited, it is necessary to add a keyboard angle adjustment function to the keyboard tray. Although there are keyboard trays with added angle adjustment mechanisms on the market, the angle is fixed by tightening the knob, which is not stable and may fail when the user presses the keyboard frequently, causing the keyboard angle to change. In this regard, users can only adjust the angle frequently, which is quite troublesome.

In this regard, the present application proposes a keyboard tray, which adjusts the pitch angle of the tray through an angle adjustment mechanism, thereby changing the flip angle of the keyboard to adapt to the different angle requirements of the user; by driving the two positioning pins 330 through a pull rope 400, the limit can be quickly released, and the locking is firm and not easy to loosen.

1 and 2, the keyboard tray in the embodiment of the present application includes a fixed frame, a movable frame, an angle adjustment mechanism, a pull rope 400 and a support plate 500, wherein the fixed frame, the movable frame and the support plate 500 constitute the main structure of the keyboard tray. The support plate 500 is used to directly support the keyboard, and an outwardly protruding baffle 510 is installed on it, which can prevent the keyboard from sliding off the support plate 500 when the support plate 500 is flipped to a larger angle. Specifically, the baffle 510 is an elastic member, which reduces the bump on the user's wrist, and can also support the user's wrist to improve the user experience.

The fixing frame includes a fixing frame body 110, which is fixed to the bottom of the desktop and provides support for other components. The fixing frame body 110 can be fixed by bolts, welding and other fixed connection methods, or by clamping and detachable connection methods. In this embodiment, the fixing frame also includes a clamping mechanism 120, which is at least two and both are connected to the fixing frame body 110, and the fixing frame body 110 is fixed to the bottom of the desktop through the clamping mechanism 120.

Specifically, the clamping mechanism 120 includes a clamping frame 121, a push screw 122, a cushion block 123 and a screwing handle 124. The clamping frame 121 is "C"-shaped and is clamped to the edge of the desktop. The clamping frame 121 is provided with a threaded hole threadedly connected to the push screw 122, and the ejection distance of the push screw 122 is adjusted by screwing the push screw 122. The cushion block 123 is installed at the first end of the push screw 122, and the screwing handle 124 is fixed to the second end of the push screw 122, so that it is convenient for the user to hold and screw. Screwing the push screw 122 can drive the cushion block 123 to approach the desktop and clamp and fix the desktop together with the clamping frame 121. The function of the cushion block 123 is to increase the contact area with the desktop, reduce the pressure acting on the desktop, and thus reduce damage to the desktop.

The movable frame includes a movable frame body 210 and a sliding mechanism 220. The slide rails in the sliding mechanism 220 are installed to the fixed frame body 110. The sliders in the sliding mechanism 220 are connected to the movable frame body 210, so that the movable frame body 210 can be pulled out from under the desktop to expose the keyboard it carries.

There are two angle adjustment mechanisms and they are symmetrically arranged. The angle adjustment mechanism includes a limit plate 310, a support rod 320 and a positioning pin 330. The limit plate 310 is connected to the movable frame body 210, the support rod 320 is hinged to the limit plate 310, and the support plate 500 is fixed on the support rod 320, so that the support plate 500 can support the keyboard for flipping. The limit plate 310 is provided with a plurality of first limit holes 311, and the distances between each first limit hole 311 and the hinge axis of the support rod 320 are equal, and the support rod 320 is correspondingly provided with a second limit hole. When it is necessary to lock the flip angle of the support plate 500, the positioning pin 330 is passed through the first limit hole 311 and the second limit hole to achieve locking.

The two ends of the pull rope 400 are respectively hooked to the ends of the two positioning pins 330. The user pulls the middle part of the pull rope 400 to simultaneously drive the two positioning pins 330 to withdraw from the first limiting hole 311 or the second limiting hole, thereby achieving unlocking, and the angle can be readjusted at this time.

Furthermore, the angle adjustment mechanism further includes a reset member 340, the two ends of which are respectively connected to the positioning pin 330 and the limiting plate 310, and are used to drive the positioning pin 330 to pass through the first limiting hole 311 and the second limiting hole. Therefore, after the positioning pin 330 is pulled out with the pull rope 400, when the user releases the pull rope 400, the reset member 340 can automatically drive the positioning pin 330 to pass through the first limiting hole 311 and the second limiting hole, so as to be re-locked.

The following is the specific working process of the angle adjustment mechanism:

Step 1: Referring to FIG. 3 , the support plate 500 is placed flat, and the positioning pin 330 is inserted into the first limiting hole 311 and the second limiting hole to achieve locking;
