Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

2. Referring to fig. 1-4, the present invention provides a technical solution: a key suspension lamp comprising: a main body (1), a key (2), a PCB substrate (3) positioned between the main body (1) and the key (2), the PCB substrate (3) is arranged on the back surface of the key (2), the main body (1) is connected with the key (2), the PCB substrate (3) is provided with an LED lamp (31) and a light touch switch (32), the main body (1) is provided with a light bearing plate (11), the middle part of the main body (1) is provided with a groove (12), the key (2) is provided with a bending part (21) facing the main body (1), the LED lamp (31) is positioned in the space formed by the bending part (21), the groove (12) is provided with a convex block corresponding to the tact switch (32), the bending part (21) is positioned on the light bearing plate (11) and is close to the groove (12), the shape of the bending part (21) is adapted to the shape of the surface of the light bearing plate (11).

The working principle is as follows: referring to fig. 3 and 4, when in use, the main body is connected with the key, and a user presses the key to the main body to drive the tact switch on the PCB substrate to abut against the bump in the groove, so that the stroke of the key is very small, and the key is triggered and lifted up when being released; the light touch switch is welded on the PCB, the PCB and the key are installed together, the key drives the light touch switch to move downwards when pressed, and the convex block in the groove props against the light touch switch to trigger action; dab switch closed switch-on, the LED lamp on the PCB base plate shines, the light that the LED lamp sent is from holding the outside transmission in one side that the light board is close to the recess, use leaded light post can weaken light brightness, this application replaces leaded light post with holding the light board, the LED lamp passes through even light lens, direct projection is on holding the light board from the button back, the button edge is brightest, luminance can weaken gradually far away more from the edge, reach gradual change effect, the portion of bending (21) in figure 4, reach natural gradual change effect. The bending part is positioned on the light bearing plate, namely the distance between the bending part and the light bearing plate is very close to or is abutted with each other and is almost contacted with each other; the bending part is close to the groove, namely the bending part is spaced from the groove, the length of the key is slightly longer than that of the groove, the length of the key is not too long, otherwise, all the light bearing plate parts are almost shielded if the length of the key is too long, and light is shielded by the key. The bending part on the key is abutted to or close to one side of the light bearing plate close to the groove, the shape of the bending part is matched with that of the concave part on the surface of the light bearing plate, when the LED lamp emits light, the bending part is abutted to or very close to the surface of the light bearing plate, specifically, the concave part is arranged on the surface of the light bearing plate, the bending part is abutted to or close to the concave part, the shape of the bending part is matched with that of the concave part, light leakage at the side edge of the key is prevented, and the lamp effect brightness is improved; when the lamp is turned off, the user continues to press the key, the tact switch is released and lifted, and the LED lamp stops emitting light. The utility model discloses hidden the installing at the button back of PCB base plate, main part and button elastic installation, the installation prevents that button activity in-process skew card is dead, and the spring is steady smooth and easy, effectively improves to press down and feels, and all parts pass through the mechanical structure assembly, and the equipment is convenient and reliable. When the lamp effect is started, the two ends of the key are provided with the lamplight setbacks, the key looks like a suspension, and the effect that the key is suspended on the surface of the light bearing plate is achieved visually.

Further, in order to make the PCB base plate install and reach hidden effect at the button back, still include fixed cover (4), button (2) orientation recess (12) are equipped with erection column (22), be equipped with on PCB base plate (3) with the first through-hole that the position and the shape of erection column (22) all correspond, erection column (22) pass behind the first through-hole through the screw with fixed cover (4) are connected, erection column (22) with fixed cover (4) hold in recess (12). When the PCB substrate is arranged on the back of the key, the first through hole is aligned with the mounting column and then inserted for installation, and then the fixing sleeve is sleeved on the mounting column and then fixedly installed by screws, so that the PCB substrate can be installed and fixed on the back of the key.

Furthermore, as shown in fig. 3, in order to connect and mount the key and the main body, the electronic device further comprises a limiting gasket (6), a guide post (23) is arranged on the key (2) towards the groove (12), a second through hole corresponding to the guide post (23) in position and shape is arranged on the PCB substrate (3), and the guide post (23) is connected with the limiting gasket (6) through a screw after penetrating through the second through hole. The key upper guide post is connected with the limiting gasket through a screw, and the limiting gasket is arranged at the bottom of the main body, so that the key is connected with the main body, and the key upper guide post is simple in structure and convenient to install.

Furthermore, as shown in fig. 3, in order to enable the main body and the key to be elastically mounted and effectively improve the pressing hand feeling, the pressing device further comprises a spring (5), wherein the spring (5) is sleeved on the guide post (23), and the spring (5) is arranged between the groove and the PCB substrate. When the key moves towards the main body, the key drives the PCB substrate to move, a spring between the PCB substrate and the groove is extruded, and when the tact switch is abutted against the lug in the groove to close the tact switch; the user continues to press the key, the spring elastic member extends, and the key leaves the main body. The spring can prevent that button activity in-process skew card is dead, and the bounce is steady smooth and easy, effectively improves to press and feels, promotes user experience.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
