Detailed Description

In order to make the objects, features and advantages of the present disclosure more apparent and understandable, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present disclosure, and it is apparent that the described embodiments are only a part of the embodiments of the present disclosure, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure.

Embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

Referring to fig. 1, an auxiliary key cap positioning device according to an embodiment of the present disclosure includes a main body 1 and a covering body 2, a surface of the main body 1 shown in fig. 1 is defined as an outer surface 13, the covering body 2 extends from an outer edge 122 of the main body 1 toward a direction away from the outer surface 13, and the covering body 2 and the main body 1 enclose a receiving groove 3 capable of receiving a key cap.

Based on this disclosed key cap auxiliary positioning device, when the key cap assembly, can correspond a smart locating hole and a smart reference post earlier and accomplish basic location, with three key cap auxiliary positioning device at least dispersion block respectively around the at least three key cap of keyboard again to guarantee the clearance between key cap and the C shell in the specification, then carry out the hot melt, take off key cap auxiliary positioning device at last, guaranteed that the clearance of key cap and C shell reaches the regulation standard. It can be understood that the number of the key cap auxiliary positioning devices installed during assembly is preferably more than four, so that the positioning accuracy is prevented from being influenced by falling off of the devices during assembly.

In the present embodiment, since the coating body 2 of the key cap auxiliary positioning device extends from the outer edge 122 of the main body 1 toward the direction away from the outer surface 13 of the main body 1, the accommodating groove 3 capable of clamping the key cap can be formed by enclosing, so that the key cap is positioned; furthermore, because cladding body 2 has thickness, can guarantee that the clearance between key cap and the C shell is cladding body 2's thickness, has solved and has taken place the skew easily after the hot melt between key cap and the C shell, and leads to the less problem that causes the card key in clearance. In addition, because the key cap auxiliary positioning device is adopted in the assembling process of the keyboard and the C shell, two fine positioning holes in the keyboard and two fine positioning columns in the C shell in the traditional assembling method are eliminated, and the tolerance of the fine positioning holes is increased to 0.2 mm.

Referring to fig. 2, in an embodiment, a handheld portion 11 is formed on a body 1 of the key cap auxiliary positioning device, a hollow portion 12 is further formed on the body 1, an inner edge 121 is formed at the hollow portion 12 of the body 1, and the handheld portion 11 is formed between the inner edge 121 and an outer edge 122.

In the embodiment, since the hollow portion 12 is disposed on the main body 1, the handheld portion 11 is formed between the inner edge 121 and the outer edge 122 of the main body 1, so that a production worker can conveniently take off the key cap auxiliary positioning device from the key cap during operation, thereby improving the production efficiency.

Referring to fig. 3, in an embodiment, a handheld portion 11 is formed on a body 1 of the key cap auxiliary positioning device, the body 1 further has an inner surface (not shown) located in the accommodating groove 3 and opposite to the outer surface 13, and the handheld portion 11 extends from the outer surface 13 toward a direction away from the inner surface and forms an included angle with the outer surface 13.

In the present embodiment, the hand-held portion 11 may be formed integrally with the main body 1, or may be connected to the main body 1 by heat fusion. Because handheld portion 11 forms the contained angle with surface 13, the key cap auxiliary positioning device is taken off from the key cap to the production workman when the operation of being convenient for, improves production efficiency. Specifically, during production, a production worker firstly grasps the handheld part 11, then pulls the key cap auxiliary positioning device, and after the uppermost coating body 2 of the key cap auxiliary positioning device is separated from the key cap, the device is pulled backwards, so that the key cap auxiliary positioning device is completely separated from between the key cap and the C shell.

Further, as shown in fig. 4 to fig. 6, a hollow-out portion 12 is further formed on the body 1 of the key cap auxiliary positioning device, an inner edge 121 is formed at the hollow-out portion 12 of the body 1, and the handheld portion 11 extends from the inner edge 121 to a direction away from the inner surface 14, and forms an included angle with the outer surface 13.

In the present embodiment, the handle 11 may be integrally formed with the body 1, and may be connected to the inner edge 121 of the hollow portion 12 by heat fusion. Because handheld portion 11 and surface 13 form the contained angle to have fretwork portion 12 on the body 1, be convenient for more the production workman takes off key cap assistance-localization real-time device from the key cap when the operation, improve production efficiency. Since the body 1 and the handle 11 should have high strength and elastic modulus, polycarbonate material or Acrylonitrile Butadiene Styrene (ABS resin) is preferred.

On the basis of the above embodiment, the initial angle between the handheld part 11 and the outer surface 13 is less than or equal to 30 degrees, so that a production worker can conveniently remove the key cap auxiliary positioning device, and the key cap auxiliary positioning device cannot be difficult to remove due to an overlarge angle, and the operability is reduced.

In an embodiment, the body 1 of the key cap auxiliary positioning device includes a first edge, a second edge, a third edge and a fourth edge, the first edge is opposite to the second edge, the third edge is opposite to the fourth edge, and the cover 2 includes a first body 21 extending from the first edge, a second body 22 extending from the second edge, a third body 23 extending from the third edge, and a fourth body 24 extending from the fourth edge.

In this embodiment, because all extend cladding body 2 on four limits of body 1, make key cap assistance-localization real-time device can more firmly reliable fix on the key cap, can not deviate from easily in process of production, increased the accuracy of location.

In an embodiment, the third body 23 and the fourth body 24 of the covering body 2 are respectively provided with a hook portion 25, and the two hook portions 25 are respectively bent toward the accommodating groove 3 and are disposed at an end of the covering body 2 away from the main body 1.

In this embodiment, by providing the hook portion 25, the key cap auxiliary positioning device can be more firmly fixed on the key cap and is not easy to be disengaged, thereby increasing the positioning accuracy.

In an implementation mode, the thickness of the cladding body 2 is 0.2 mm-0.5 mm, preferably, the thickness of the cladding body 2 is set to be 0.29 mm-0.31 mm, so that the gap between the keycap and the C shell can meet the production requirement of being larger than or equal to 0.2mm, the problem that the keycap and the C shell are not clamped due to deviation after hot melting is ensured, and the experience of a user is improved.
